NATIONAL WEATHER SERVICE GRAND FORKS ND
253 PM CDT TUE JUL 26 2011
.SHORT TERM...SEVERE THUNDERSTORMS AND HEAVY RAIN POTENTIAL INTO
TONIGHT WILL BE THE MAIN CONCERN. 12Z MODELS ALL
SIMILAR...ALTHOUGH GFS LIKELY SUFFERING FROM CONVECTIVE FEEDBACK
AND WILL NOT FOLLOW FOR DETAILS.
TRENDS CONTINUE TO APPEAR ON TRACK FOR A SIGNIFICANT EVENT LATER
THIS AFTERNOON AND TONIGHT. CURRENT ACTIVITY WILL LIKELY HOLD
TOGETHER AND GRADUALLY MOVE EAST...ESPECIALLY ACROSS THE NW FA
THROUGH THE AFTERNOON HOURS. THIS AREA LOCATED IN AREA OF STRONG
700MB WARM AIR ADVECTION ON EDGE OF ELEVATED INSTABILITY. GIVEN
STRONG DEEP LAYER SHEAR ISOLD SEVERE POSSIBLE...BUT SHOULD BEHAVE
GIVEN WEAKER INSTABILITY (AT LEAST UNTIL ELEVATED INSTABILITY
INCREASES AFT 00Z).
MAIN EVENT WILL BE LATER THIS AFTERNOON AND OVERNIGHT. MODEL
SIGNALS SUGGEST TWO AREAS OF CONCERN. MAIN AREA OF CONCERN WILL BE
ACROSS THE SW FA WHERE SPC PAINTS A MODERATE RISK. SFC BASED
(MLCAPE) INSTABILITY WILL INCREASE TO 2000-3000 J/KG INTO THIS
AREA BY 00Z-03Z. 500MB SPEED MAX AND SHORTWAVE SHOULD INITIATE
STORMS ACROSS SOUTHCENTRAL NORTH DAKOTA AND NORTHCENTRAL SOUTH
DAKOTA MID-AFTERNOON. THIS ACTIVITY SHOULD MOVE EAST INTO THE SW
FA BY LATE AFTERNOON/EARLY EVENING WITH ALL FORMS OF SEVERE WX
POSSIBLE. PWATS AROUND TWO INCHES LEADS TO FLASH FLOOD POTENTIAL
(AND THUS FLASH FLOOD WATCH). THE OTHER AREA OF CONCERN WILL BE
NORTH...WHERE STRONG WARM AIR ADVECTION FROM 40KNT LOW LEVEL JET
WILL BE PRESENT BY 03Z AND CONTINUE THROUGH MUCH OF THE NIGHT.
850MB CAPE 1500-2000 J/KG AND STRONG DEEP LAYER SHEAR WILL LEAD TO
POTENTIAL LARGE HAIL...STRONG WINDS...AND HEAVY RAINFALL. FLASH
FLOOD GUIDANCE A BIT HIGHER ACROSS THIS AREA...SO NO PLANS FOR
EXPANDING CURRENT FLASH FLOOD WATCH.
FAST ZONAL FLOW WED-FRI...BUT DRY AIRMASS WILL LIMIT THUNDER
POTENTIAL. TEMPERATURES NEAR NORMAL.
.LONG TERM.../FRI NIGHT THROUGH TUE/
THE LONG TERM MODELS SOMEWHAT AGREE WITH THE UPCOMING WEEKENDS
WEATHER BUT QUICKLY DIVERGE FOR EARLY NEXT WEEK. A ZONAL PATTERN
WILL ALLOW A COUPLE OF WAVES TO PASS THROUGH THE AREA IN THE DAY 4
TO DAY 7 TIMEFRAME. A WEAK WAVE IS PROGGED TO MOVE THROUGH FRI NIGHT
INTO SAT...THUS LOOKING FOR SOME ISOLD SHOWERS/TSTMS. FOR
SUNDAY...GFS BRINGS A SFC HIGH OVER THE AREA WHILE THE ECMWF KEEPS
THE HIGH WELL TO THE NORTH AND SOME POPS REMAIN ESPECIALLY IN
EASTERN ZONES. BEYOND SUN...MODELS DIVERGE WITH TIMING OF
SYSTEMS...BUT DO EXPECT SOME ACTIVITY IN THE DAY 6 TO DAY 7
TIMEFRAME.
