.SHORT TERM...TONIGHT.
THUNDERSTORM POTENTIAL WILL BE THE MAIN PROBLEM IN THIS FORECAST AS
PLENTY OF INSTABILITY AROUND BUT FORCING MECHANISMS LIMITED. HAVE
LEFT OUT THUNDER IN TAFS AT THIS TIME DUE TO UNCERTAINTY IN TIMING
AND LIMITED EXTENT OF COVERAGE. OUTSIDE OF STORMS VFR CONDITIONS
EXPECTED THROUGH THE PERIOD.
.LONG TERM...SATURDAY THROUGH FRIDAY.
SHORTWV ENERGY THAT WAS MOVING ACROSS SWRN CANADA PER FRIDAY AFTN

SRLY FLOW RETURNS/STRENGTHENS IN RESPONSE LATE TNGT/SAT. WITH
APPARENT LACK OF UPPER SUPPORT BEFORE FRONT PASSES THROUGH FRI
EVENING/NGT WILL LEAVE PCPN OUT OF FCST SAT...ALTHOUGH VARIOUS
FORECAST SOUNDINGS INDICATED SOME CHC OF ELEVATED ACTIVITY BEFORE
CAP STRENGTHENS SAT AFTN. MADE LTL CHANGES TO TEMPS/DWPTS ON SAT.
CONDITIONS POSSIBLY SIMILAR TO WED WITH MAV/MET GUIDANCE AND FCST
SOUNDINGS PROBABLY UNDER FORECASTING DWPTS...ALTHOUGH ATTM DID NOT
BRING THEM UP TO 80 AS WED. NONETHELESS...HEAT ADVISORY CRITERIA
LIKELY WILL BE REACHED AND AN ADVSRY ISSUED ALL ZONES. FRONT WILL BE
CROSSING CWA AFTER MAX HEATING INSTEAD OF DURING IT LIKE WED...BUT
ACTIVITY SHOULD BE ONGOING N OF CWA BY 00Z AND WOULD THINK IT WL
BUILD SW ALONG FNT DURING THE EVENING WHICH SHOULD AID IT PUSHING IT
FARTHER SE THAN MODELS SUGGEST WITH HIGHER POPS THAN GUIDANCE.
BOOSTED POPS...SPCLY NERN ZONES WHICH WILL BE CLOSER TO EDGE OF WARM
MID LVL TEMPS/STRONGER CAP. STRENGTHENING COLD POOL DRIVEN MCS AND
STRONG WINDS POSSIBLE AGAIN SAT NGT WITH STORMS.
GFS/NAM SOUNDINGS SUGGEST SOME MID CLOUDS AND POSSIBLE
ACCAS/SHOWERS/ISOLD TSTMS LINGERING N OF THE FRONT ON SUN POSSIBLY
SPREADING NWD SUN NGT/MON AS LOW LVL JET BECOMES SOUTHERLY AND
INCREASES. THUS MADE LTL ADJUSTMENTS TO POPS ALTHOUGH DID TRIM
BACK HIGHS ON SUN NRN ZONES SINCE THERE WAS DECENT AGREEMENT BETWN
GFS/NAM FCST SOUNDINGS ON HIGH POSSIBLY GETTING NO WARMER THAN
LOWER 80S. APPEARS WARM FRONT WILL LIFT AT LEAST N OF SERN NEBR ON
MONDAY AND THUS BROUGHT LOWER 90S TO HIGHWAY 30 WHICH COULD PROVE
CONSERVATIVE IF CLOUDS DON/T LINGER.
FORECAST AREA LOOKS TO REMAIN ON RING-OF-FIRE IN TUE THROUGH FRI
PD OF NEXT WEEK WITH A CHANCE OF NIGHTTIME CONVECTION CATCHING NRN
ZONES EACH NIGHT PER GFS/ECMWF. HOWEVER...OVERALL UPPER HGTS
REMAIN ABOVE NORMAL WHICH SHOULD KEEP TEMPS ABOVE NORMAL AS WELL
WITH MANY LOW/MID 90S AND POSSIBLE ADDITIONAL HEADLINES NEEDED FOR
HEAT. DEBRIS/FRONT SHOVED SWD BECAUSE OF CONVECTION WOULD BE A
HINDRANCE TO BOTH BUT IMPOSSIBLE TO COUNT ON THAT FAR OUT.
