Area forecast discussion 
National Weather Service North Platte NE 
212 am CDT sun Mar 21 2010 


Discussion... 
ridge of high pressure will begin building east from The Rockies 
into the Central Plains today...and skies will be sunny. A small 
increase in cirrus clouds are expected by late afternoon 
however...as upper level moisture tops the crest of the ridge and 
spills southeastward into the plains. High temperatures today will be about 
10 to 15 degrees warmer than those of Sunday...as southwest winds 
transport warmer air into the region. A downslope component will 
also add a boost to temperatures...and highs should reach the 50s across 
all of western and central Nebraska. 


Tonight...southwest winds will stay up a bit...and this will help 
keep temperatures relatively mild. Lows will range from the middle 20s 
southwest to lower 30s north central. 


Monday...a cold front will slip south into the northern plains...and 
just ahead of the front west to southwest winds will really help the 
area warm nicely. Expecting 60s area wide...with perhaps a 70 degree 
reading from southwest into west central Nebraska just ahead of the 
front. By late Monday afternoon and evening...will maintain the 
slight chance probability of precipitation for an isolated T-storm across the Panhandle. 
Latest 00z NAM continues to indicate some weak middle level 
instability...it also indicates some surface based instability...but 
feel the 50s dew points it develops during the afternoon ahead of 
the cold front across the southern Panhandle and southwest Nebraska are 
way overdone. Actually having a hard time finding much for a trigger 
at this point...but there will likely be enough ascent ahead of the 
trough digging into the northern rockies that an isolated storm 
cannot be ruled out. 


Front moves through the area early Monday evening...with cooler 
conditions Tuesday and Wednesday. Models continue to dig a trough 
southward through The Rockies and into the Southern Plains Tuesday 
into Wednesday. Best lift/dynamics stay west and southwest of the 
area...but some light precipitation remains a possibility across the 
western half of Nebraska. Ridging to move east into the plains by 
late week with a return to warmer weather once again.

Aviation...for the kvtn and klbf terminals through 12z Monday... 


Ridging aloft will build into the Central Plains over the next 24 
hours with unlimited visibilities and clear skies expected. Some 
thin invading cirrus cloudiness at or above 25000 feet above ground level will begin to 
spread into western Nebraska after 06z tonight

Lbf watches/warnings/advisories...none.
