32 F hr. fxus61 kcle 111033 afdcle area forecast discussion national weather service cleveland oh 633 am edt tue mar 11 2014 synopsis... a weakening cold front will sag across the area today. this front will stall over central or southern ohio this evening and become the path for low pressure to move along late tonight into wednesday. high pressure will build in on thursday. && near term /until 6 pm this evening/... only minor changes to hourly temperatures have been made. previous discussion... a weakening cold front will sag across the area today. this should provide for a cooler day than yesterday. however the region is starting rather warm so we have gone slightly higher than guidance highs. still looks like most of the region will be near or above 50...warmest across the south. as the flow comes off of lake erie this afternoon temperatures will likely fall. we will need to monitor for some fog development as the chilled air from the ice covered lake moves onshore. && short term /6 pm this evening through friday night/... low pressure will move near the ohio river valley tonight into wednesday. this will bring rain into the region overnight. since the models are slightly further north with the low track it appears the rain may persist into wednesday morning from the central county warning area into nw pa. this may end up cutting into the snowfall amounts. we have nudged the heavier snow a bit further north with this forecast package but have not changed the watch area at this time. the reason for leaving it a watch is that there is still uncertainty in the track of the low. there are still a couple solutions that move the track even further north. the main concerns for the county warning area are the nw and ne corners. these two areas have the best shot at seeing the significant snow...especially with an even further north wobble of the track. after an area changes over to snow late tonight into wednesday there will likely be a quick burst with 2 to 4 inches rapidly accumulating. this may impact the evening commute from cleveland to mansfield and locations to the east. we will then see how much lake effect snow can occur in the wake of the low. winds will be gusty in the wake of the low and could exceed 40 mph at times. as the snow tapers off the cold air will continue to filter into the area with lows dipping into the single digits by thursday morning. thursday will be a cold day with lake effect snow showers for ne ohio into nw pa. as high pressure slides east of the area on friday we will have increasing southwesterly flow. any snowpack will slow the warming on friday but it still appears many locations will be into the 40s. however the upper 30s may occur across nw ohio and nw pa if the heavier snow occurs. && long term /saturday through monday/... a cold front will push south across the area on saturday with a chance of lake effect rain/snow showers...mainly in the snowbelt as the trough shifts through. the airmass will dry out as high pressure builds over the central great lakes on sunday with north to northeast flow resulting in below normal temperatures to end the week. && aviation /06z tuesday through saturday/... southwest winds over the area will decrease towards 12z...possibly becoming light and variable in nw ohio. as this occurs...visibilities could drop in br towards dawn...mainly at tol/fdy where snowmelt is contributing moisture to the boundary layer. not expecting fog but can not entirely rule it out. otherwise winds will eventually shift around to the north/northeast by early evening on tuesday ahead of low pressure approaching the mid-mississippi valley. slowed down the arrival of precipitation with the approaching system...leaning more towards the nam. eventually will see rain begin at all sites tuesday night...with aviation conditions deteriorating as we transition to a wintry mix on wednesday. outlook...non vfr becoming widespread late tuesday night and continuing into wednesday night especially in the snow belt. non vfr friday night into saturday. && marine... southwest winds of 10 to 20 knots will decrease through midday then shift to the north by this evening. northerly winds will undergo rapid strengthening from late tonight into wednesday as low pressure deepens as it tracks through the ohio valley. the gradient really tightens up over the southern lakes region between the system to the south and high pressure strengthening over lake superior. a gale watch has been issued for the whole lake for wednesday with 35-40 knot gales expected. gusts to 50 knots will be possible and some movement of the ice sheet is expected. winds will drop off considerably by thursday as high pressure builds east across the region. southwesterly winds near 20 knots will develop on friday ahead of low pressure passing north of the lakes. the associated cold front will push south across the lake on saturday. && hydrology... flow into the rivers will continue again today with some snow melt flowing into a few of the area rivers. we are continuing to monitor an ice jam along the chagrin river near willoughby. if it continues to rise we may need to issue an areal flood warning. if you live near the chagrin take any precautions needed to protect your property. otherwise there will be a period of rain tonight into wednesday morning that will provide additional flow to all of the rivers. any ice jams will need to be monitored closely. law enforcement and emergency management from counties with rivers that flow into lake erie will be needed to help with warning decisions. another concern that could develop is the strong winds on the west side of the low on wednesday. the strong northerly winds may bring significant amounts of ice on lake erie back into the mouth of the rivers and could add to the ice jam problems. && cle watches/warnings/advisories... oh...winter storm watch from late tonight through late wednesday night for ohz010>014-089.

pressure...strengthening in the central plains...will move across the lower ohio valley early wednesday. arctic high pressure will fill in for thursday. another low will move through the great lakes on friday however the warm front ahead of the low will force the arctic air out of the region. && near term /until 6 am wednesday morning/... upgraded watch to a warning and added the far southeast into an advisory. started the warning overnight northwest and near morning or during the morning elsewhere. clouds will fill in through the evening with rain spreading in from the west overnight. followed the sref/nam combination through the short term. noted that the 12z run was just a bit cooler than 06z run. still...through 06z expect any/all precip will be rain. by 09z the nam has the 0c 850mb temp from near erie to kcle to fdy however bufkit forecast soundings show a nose of warmer air around 800mb. this ribbon of warmer air shows up also across the rest of the area as well. expect precip therefore to transition to sleet and freezing rain before changing to snow. worded in the zones as a chance...however believe it will be a decently good chance for at least an hour or two of the mix. the only snow accum for the overnight will be in the northwest with 1 to 3 at tol and around 1 at kfdy. for late eve update...continued to slow temps drop some more with this update and likewise slowed transition to wintry mix to correspond to temp adjustment. also adjusted qpf for second half of the night to lower in the inland east as most precip will stay further north or west thru 12z. && short term /6 am wednesday morning through friday night/... continued to follow the nam/sref. by 12z expect precip to be snow across the northwest third of the area with freezing rain and sleet occurring near a line from mnn-cle-keri. the band of mixed precip will shift southeast through the morning exiting the yng area around 18z. snow will be heavy at times across the northern tier through the day with dry air moving in from the northwest mid/late afternoon. winds will increase from the north behind the low reaching 20 to 30 mpg with gusts into the 40s. could see gusts to near 50 esp near the lakeshore. will end precip wednesday evening/early night wednesday night northeast as the dry air moves in with high pressure. the high will be in place thursday with a warm front moving through the region. && long term /saturday through tuesday/... strong warm advection progged for friday as a warm front lifts north across the great lakes. high clouds are progged to increase. did not go as high on the temps (40s to near 50 for highs) as might be expected since we have to melt snow. looks like a series of cold fronts or troughs will move through on the weekend. the first weak cold front or prefrontal trough would be later friday night. might be cold enough for snow but will mention a chance of rain showers as well since there should be a decent southwest flow ahead of the front/trough. the front or trough may be east of the area saturday morning bit i am not convinced the models have resolved the weak systems very well. with the trough deepening aloft will keep a chance of rain/snow showers mainly across ne oh/nw pa on saturday. it appears that the arctic front will slide south across the area saturday evening or saturday night and kept a small chance of snow showers for ne oh/nw pa. the ecmwf still indicates a chance for a wave on the front by sunday night into monday. the gfs builds in the arctic high. will keep a small chance of lake effect snow showers/flurries and keep a low pop elsewhere in case there might be a wave on the front. the latest ecmwf brings yet another wave on tuesday but am inclined to keep the forecast dry tuesday with a moderation in temperatures. && aviation /00z thursday through sunday/... everything looks on track for the surface low to move along the ohio river on wednesday. all models seem to agree on this. clouds will thicken and lower tonight with some isolated light showers early tonight and then rain developing after 07z and spreading east quickly. the tough question is how long will it take to go from rain to snow with some freezing rain and sleet in between. at this time going with 1 to 2 hours. conditions will lower to mvfr after the rain starts and then as soon as the snow starts ifr. the heaviest snow will be at tol...fdy...cle and eri. conditions will begin to improve from the west by mid to late afternoon. outlook...mvfr wednesday night...and lingering into thursday for ne oh/nw pa. non vfr possible friday night into sunday. && marine... winds will come around from the north and northeast tonight on lake erie as low pressure develops over the plains states. gale force winds will develop wednesday morning as the gradient increases between the surface low over the ohio valley and an arctic high pressure area in canada. the winds will decrease quickly wednesday night into thursday as the arctic high settles across the lakes. a clipper low pressure from central canada will slide down across the great lakes friday into saturday leading to yet another arctic high pressure
