Area forecast discussion, Mar 24, 1:47 AM MDT, 9 hours 3 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
247 AM CDT MON MAR 24 2008
.SYNOPSIS...
SFC ANALYSIS AT 06Z SHOWS HIGH PRESSURE LOCATED FROM IOWA
SOUTH/SOUTHWEST INTO TEXAS. MID LVL RIDGE OBSERVED IN 00Z UPR AIR
DATA AND RECENT WV IMAGERY IS APPROACHING THE HIGH PLAINS...WITH A
LARGE PLUME OF CIRRUS SPREADING EAST INTO THE NEB PANHANDLE. LEE
TROUGH IS BEGINNING TO FORM AS UPR LVL TROUGH CONTINUES DEPARTING
TOWARDS THE EAST COAST AND FAST WESTERLY MID LVL FLOW SPREADS
TOWARDS THE FRONT RANGE.
&&
.DISCUSSION...
EVOLUTION OF FIRE WEATHER INGREDIENTS WILL NEED TO BE MONITORED
DURING MONDAY AFTERNOON AS SFC TROUGH AXIS BEGINS TO SHIFT EAST OFF
OF THE HIGHER TERRAIN. REFER TO FIRE WX DISCUSSION BELOW FOR FURTHER
DETAILS. PREVIOUSLY MENTIONED CIRRUS PLUME IS EXPECTED TO SPREAD
EAST ACROSS THE REMAINDER OF THE CWA THROUGH MONDAY
AFTERNOON...WHICH COULD IMPACT SFC HEATING. LATEST MET GUIDANCE
INDICATES MID/UPR 60S FROM SOUTHWEST NEB NORTH TO KVTN...WITH TMPS
CLOSER TO 60 NEAR KONL. GFS/NAM ALSO SHOW A WEAK SFC LOW MOVING
EAST ACROSS SOUTHERN SD MONDAY AFTERNOON...AND THIS MAY FAVOR
SLIGHTLY WARMER TEMPERATURES NEAR KVTN. COLD FRONT WILL THEN SLIDE
SOUTH OF THE CWA MONDAY NIGHT...LEADING TO MORE SEASONABLE HIGH
TEMPERATURES TUESDAY AFTERNOON. MODEL GUIDANCE HAS BEEN TRENDING
COOLER FOR WEDNESDAY AS SFC LOW PRESSURE SYSTEM BEGINS TO TAKE
SHAPE ACROSS THE SOUTHERN HIGH PLAINS. THIS WILL LEAD TO EASTERLY
UPSLOPE FLOW ACROSS MUCH OF THE CWA. WARMEST TEMPERATURES
WEDNESDAY AFTERNOON WILL LIKELY RESIDE CLOSE TO INVERTED LEE
TROUGH WHILE MORE WIDESPREAD CLOUD COVER WILL KEEP HIGHS IN THE
UPR 40S TO MID 50S OVER NORTH CENTRAL NEB /IF NOT COLDER...AS WE
ARE STILL ABOVE GUIDANCE IN SOME SPOTS/.
ON THURSDAY...UPR LVL TROUGH AND ASSOCIATED 130 KT WESTERLY H25 JET
IS EXPECTED TO BECOME POSITIONED OVER THE WESTERN HALF OF THE
CONUS...WITH SFC LOW FORMING OVER THE SOUTHERN HIGH PLAINS. A WARM
FRONT WILL EXTEND EAST FROM THE SFC LOW INTO THE OH VALLEY REGION
BY 12Z THURSDAY. NORTH OF THE WARM FRONT...STRONG LOW LVL WAA AND
ISENTROPIC LIFT ARE FCST BY BOTH NAM AND GFS TO BECOME MAXIMIZED
ACROSS NEB BETWEEN 00Z-12Z THURSDAY. MOIST UPGLIDE IS DEPICTED ON
300 K SFC...AND FCST SOUNDINGS SHOW DEEP LAYER OF SATURATION
WEDNESDAY NIGHT...WHICH LEADS TO INCREASING CONFIDENCE THAT PRECIP
WILL OCCUR ACROSS MUCH OF THE CWA ON THURSDAY. IN ADDITION...A
PLUME OF STEEP MID LVL LAPSE RATES WILL OVERSPREAD THE REGION
LEADING TO A CONDITIONALLY UNSTABLE ATMOSPHERE. IF SATURATION CAN
OCCUR IN THE 600-700 MB LAYER...THEN 300-400 J/KG OF CAPE COULD BE
ACHIEVED...WHICH WOULD LEAD TO ELEVATED THUNDERSTORM ACTIVITY AS
WAA BECOMES MAXIMIZED WEDNESDAY NIGHT. HOWEVER...DECIDED TO LEAVE
OUT MENTION OF THUNDER AT THIS POINT DUE TO THE POSSIBILITY OF
ADDITIONAL MODEL VARIABILITY DURING THE NEXT FEW DAYS.
PRECIP TYPE WEDNESDAY NIGHT ALSO APPEARS PROBLEMATIC...ESPECIALLY
ACROSS THE EASTERN HALF OF THE CWA. GFS FCST SOUNDINGS SHOW A DEEP
SATURATED ISOTHERMAL LAYER NEAR THE SFC UP THROUGH 600 MB WHICH
RESIDES AT OR JUST BELOW FREEZING. THIS THERMODYNAMIC PROFILE
COULD FAVOR A RAIN/SNOW MIX...ALL SNOW...OR EVEN SLEET. WENT WITH
A RAIN/SNOW MIX AT THIS POINT...THOUGH A COMPLETE CHANGE OVER TO
FROZEN PRECIP IS A POSSIBILITY. BELOW NORMAL TEMPERATURES ARE THEN
EXPECTED THURSDAY AFTERNOON...WITH POST FRONTAL LOW LVL CLOUDINESS
AND EASTERLY COMPONENT TO LOW LVL FLOW PERSISTING. VERY LARGE
SPREAD IS NOTED IN MREF HEADING INTO FRIDAY...LEADING TO LOW FCST
CONFIDENCE. THUS...DID NOT MAKE SUBSTANTIAL CHANGES FOR FRIDAY.
&&
.AVIATION...
A WARM FRONT AND SURFACE TROUGH CROSSING WESTERN NEBRASKA WILL
BRING SOUTH TO SOUTHWEST WIND OF 10-15KT GUSTING TO OVER 20KT...BUT
ONLY HIGH CLOUDINESS IS EXPECTED. AS A RESULT...UNRESTRICTED FLIGHT
CONDITIONS ARE INDICATED IN THE VALENTINE AND NORTH PLATTE TERMINAL
FORECASTS.
&&
.FIRE WEATHER...
CURRENT FORECAST IS STILL ON TRACK WITH LOW HUMIDITY AND
MODERATE WIND OVER WESTERN NEBRASKA. THE CURED GRASS SHOULD BE
PRETTY DRY BY NOW...AND IT IS UNLIKELY THAT SIGNIFICANT GREENING HAS
OCCURRED IN THE LAST FEW DAYS. SINCE THE VALUES OF WIND AND HUMIDITY
ARE MARGINAL...CURRENT THINKING IS THAT THERE IS SOME FIRE DANGER
BUT NOT ENOUGH FOR ISSUING OF ANY SPECIAL FIRE WARNINGS. WE WILL
KEEP THE MENTION OF FIRE DANGER IN THE HAZARDOUS WEATHER OUTLOOK
THOUGH...AS THE SITUATION WILL NEED TO BE MONITORED.
&&
.LBF WATCHES/WARNINGS/ADVISORIES...NONE.
