will move east across the ohio valley this morning while high pressure builds southeast into the region this afternoon and evening. another weak area of low pressure will move southeast over the area tonight. high pressure will move southeast and then east across the gulf coast states on friday. another low pressure system will move east across central ontario canada and force a cold front through the area on saturday. && near term /until 6 pm this evening/... light snow continues to occur across the area this morning. expecting light accumulations and gradually dissipating from west to east across the area. no real major changes to forecast with this update. previous discussion... overall pattern remains unchanged at this time as ridge continues on the west coast and broad upper level trough continues over the eastern united states. a surface low pressure system will move east across the ohio valley this morning and spread some light snow into mainly the southern portions of the forecast area. flow should support the potential for a multi lake snow band from lake huron across lake erie into eastern ohio and northwest pennsylvania. expecting the lake effect to be light as it continues through the day today. snow across the south should remain light as well and the bulk of it should remain south of the forecast area. temperatures are going to be a problem today as some fairly strong cold air advection takes place. the cold air will start to push into the region this morning and winds are expected to increase to between 10 and 20 mph. this in combination with temperatures around 10 degrees will cause wind chills to drop below the -10 threshold for wind chill advisories. so...will go ahead and hoist the wind chill advisory for today from 15z through wednesday morning at 16z. && short term /6 pm this evening through friday night/... wind chill temperatures will still be an issue overnight tonight into wednesday morning. temperatures are expected to drop down to around 0 to -4 f for lows. even though winds are expected to diminish during the night a bit...wind chills will still be below the -10 threshold. will keep the winter weather advisory through the night into wednesday morning. expecting some warming to take place wednesday morning along with diminishing winds and we will likely be able to drop the advisory for a period during the rest of the day wednesday. this will be short lived as temperatures will dip to the single digits with winds increasing again for wednesday night. this will bring wind chills back down to below -10 especially across the south. it will be close across the northern portions of the area but will keep the advisory in for that area as well in case winds are a bit stronger and temperatures are a bit colder. the best chance for very cold wind chills will come thursday night into friday morning but more on that as it approaches. as high pressure builds east across the area tonight...lake effect snow shower activity will gradually come to an end as flow shifts to a westerly and then southwesterly direction. then...another low pressure system will slip southeast across the great lakes region on wednesday and spread more snow into the area. best chance will be wednesday evening with weak warm air advection ahead of the low and best upper level dynamics arriving at this time. as low pressure pulls out to the east...a trailing surface trough of low pressure will linger across the forecast area through thursday. then moisture associated with the trough will exit stage right leaving behind adequate flow and lake moisture to produce lake effect snow over the northeast and fair weather elsewhere. yet another storm system will approach from the northwest friday into friday night and this storm system will be a repeat of all the other systems and spread some moisture into the area along with vigorous upper level positive vorticity maximum over the region. this system appears that it will be a bit more potent than the previous one with a bit more moisture to work with as well. will be keeping an eye on this system for possible headlines. the next bulls eye for cold temperatures arrives on thursday with early highs in the morning and then falling through the day. will try to trend temperature in that direction for now. this should be the coldest day of this forecast period as warmer air tries to return ahead of the next system on friday. && long term /saturday through monday/... little change in the extended forecast with much below normal temperatures and periods of snow. deep upper level low remains nearly stationary over hudson bay with a series of short waves moving across the area. both gfs and ecmwf very similar in timing with arctic front moving through on saturday. after that the timing of the short waves between the models out of sync. for now will just continue with chance pops through the period...especially in the snowbelt east of cleveland. && aviation /12z tuesday through saturday/... snow over the area will gradually taper off from the nw as the surface low now over virginia...moves off the mid atlantic coast this afternoon. expect most locations to improve to vfr this afternoon. outlook...non vfr possible again wednesday afternoon through thursday night...and again saturday in -sn. && marine... the lake is mostly ice covered although there are a few open areas mainly east...and along the south shore. northeast flow over the lake will shift to the north today...and then to the southwest wednesday as high pressure moves across the ohio valley. winds shift back to the northwest wednesday night as a clipper moves across the lake. winds again back to the southwest friday as another area of high pressure moves across the tennessee valley. && cle watches/warnings/advisories... oh...wind chill advisory from 10 am this morning to 11 am est wednesday for ohz003-006>014-017>023-027>033-036>038-047- 089. pa...wind chill
