AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
834 PM CDT TUE JUL 26 2011
.DISCUSSION...FORECAST CHALLENGE FOR UPDATE CONCERNS CONVECTIVE
POTENTIAL AND HEAVY RAIN. DEEP CONVECTION SO FAR THIS EVENING
ACROSS OUR FA HAS BEEN CONFINED TO THE NORTH/SOUTH DAKOTA BORDER
AREA JUST NORTH OF APEX OF ARCING WARM FRONT FROM NE SD INTO SW MN.
EXPECT CONVECTION TO PROPAGATE ESE ALONG WARM FRONT IN FAVORED
MOISTURE AND INSTABILITY AXIS. PRIMARY THREAT MAY BE EVOLVING INTO
MORE OF A WIND EVENT WITH ISOLD TORNADOES POSSIBLE. FARTHER NORTH
A QUESTION MARK. CLOUDS HAVE GREATLY LIMITED INSTABILITY/CAPE AS
MOST OF THE FORECAST AREA CURRENTLY QUITE STABLE AND ANY CAPE
CONFINED TO ND/SD BORDER AREA. RUC INTENSIFIES LOW LEVEL JET/LOW
LEVEL WARM ADVECTION TOWARDS MIDNIGHT WITH SURFACE LOW CURRENTLY
BETWEEN MBG/PIR LIFTING INTO SE ND. FOR THIS AM HESITANT TO DROP
POPS SIGNIFICANTLY. ORIENTATION OF THE LOW LEVEL JET LATER TONIGHT
WOULD FAVOR BEST CHANCE FOR ADDITIONAL DEVELOPMENT INTO WESTERN
MINNESOTA AS WELL AS FAR SOUTH.
00Z ABR SOUNDING INDICATING PRECIPITABLE H2O VALUES OF
2.10 INCHES SO HEAVY RAIN POTENTIAL STILL EXISTS AND WILL MAINTAIN
FLASH FLOOD WATCH. DID LOWER QPF ACROSS ALL BUT FAR SOUTHERN INTO
NE FA WHICH WILL HAVE AN IMPACT ON FUTURE FLOOD FORECASTS.
OTHER THAN POP/QPF ADJUSTMENTS REMAINDER OF FORECAST LOOKS GOOD
WITH MINIMAL CHANGES.
