   valid 181200z - 191200z

   ...there is a slgt risk of svr tstms for parts of the cntrl/srn high
   plains tue afternoon/evening...

   ...synopsis...
   an amplified upper-level trough will penetrate inland in the
   west...with a downstream ridge shifting gradually ewd from the
   rockies to the high plains. a shortwave impulse will progress ewd
   across srn quebec towards the canadian maritimes within a broader
   sern canadian trough. a lingering vort max will dampen as it ejects
   e/sewd from the upper ms valley to the upper oh valley by early wed.
   at the surface...a weak cold front should push sewd the northeast
   and midwest. a composite front/outflow should become
   quasi-stationary across the srn plains. 

   ...cntrl/srn high plains...
   although abundant convection in preceding days across the plains
   will yield pockets of an overturned air mass across the lower
   plains...low-level upslope flow will continue and should maintain
   50s dew points in the lee of the srn rockies. scattered tstms should
   again form by late afternoon along the higher terrain and spread
   e/sewd into the evening. with a belt of confluent mid/upper-level
   flow undercutting a more prominent ridge to the n...deep-layer shear
   will be sufficient for supercells with primary initial risk of large
   hail. a localized tornado threat is also apparent...where low-level
   srh should be enhanced by the probable presence of a composite
   front/outflow in the wake of the preceding days of convection.
   upscale growth into one or more mcs/s is again possible with an
   increasing risk for severe wind during the evening.

   ...nrn rockies into parts of the nrn/cntrl high plains...
   low-level upslope flow will strengthen in advance of the upper-level
   trough entering the west....which should yield middle 40s to lower
   50s surface dew points being maintained at peak diurnal mixing along
   the lee of the rockies. with steep tropospheric lapse
   rates...moderate buoyancy should develop. however...most of the nrn
   into the cntrl high plains will remain beneath a mid-level ridge.
   this will serve to marginalize deep-layer shear for supercells and
   probably limit tstm coverage /especially with nrn extent/. farther w
   across the nrn rockies...mid-level s/swlys will strengthen with
   approach of the trough which could support a couple of marginal
   supercells late in the day. 

   ...northeast to midwest...
   moderate mid-level wlys will persist in association with
   the broad trough centered over sern canada...with pockets of
   stronger flow in association with impulses departing srn quebec and
   the other approaching from the upper ms valley. guidance suggests
   that isolated to scattered tstms will form along a weak cold front
   and perhaps along a trough in the lee of the appalachians.
   however...guidance does differ substantially with the degree of
   buoyancy along the front...with the nam appearing to be more
   unstable with greater insolation. although mid-level lapse rates
   should be fair to poor...the most favorable wind profiles for
   supercells will exist across the northeast. portions of this region
   may require an upgrade to slight risk if it appears that moderate
   buoyancy may indeed develop.
