AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND

.UPDATE...
ISSUED AT 836 AM CDT WED JUL 23 2014

A FEW SHOWERS ARE REACHING INTO THE FAR SOUTHWEST FA NOW. THESE
CONTINUE TO SHRINK IN OVERALL COVERAGE SO DO NOT EXPECT THEM TO
LAST FOR TOO MUCH LONGER. THEREFORE ADDED THEM TO THE FORECAST
FOR THE FAR SOUTHWEST FOR ONLY ANOTHER HOUR OR SO.

&&

.SHORT TERM...(TODAY THROUGH THURSDAY)
ISSUED AT 335 AM CDT WED JUL 23 2014

THERE WILL BE A BATTLE BETWEEN THE DRY SURFACE HIGH AND SHORTWAVES
RIDING OVER THE UPPER RIDGE AND INTO THIS REGION. 00Z MODELS IN
DECENT AGREEMENT AND WILL USE A BLEND FOR DETAILS. MOST GUIDANCE
SUGGESTS TODAY WILL BE DRY...WITH ISOLD/SCATTERED SHOWERS ON
THURSDAY. INSTABILITY WILL REMAIN VERY WEAK...LIMITING THE
POTENTIAL FOR STRONG STORMS. TEMPERATURES NEAR OR SLIGHTLY BELOW
NORMAL VALUES.

.LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 335 AM CDT WED JUL 23 2014

THURSDAY NIGHT-FRIDAY NIGHT...A STRONG UPPER LOW PROPAGATING
ACROSS SOUTHERN CANADA WILL BE JUST NORTH OF MONTANA BY FRIDAY
AFTERNOON. SOUTHERLY LOW-LEVEL FLOW AHEAD OF THIS FEATURE WILL
INCREASE MOISTURE AND RESULTANT INSTABILITY. A SFC TROUGH WILL
PROPAGATE ACROSS THE REGION DURING THIS PERIOD...ALONG WITH PRECIP
CHANCES. THE BEST THUNDER POTENTIAL WILL BE FRIDAY
AFTERNOON/EVENING DURING PEAK HEATING. ALTHOUGH LOW-LEVEL FORCING
WILL BE WEAK...THE POTENTIAL FOR STRONG TO SEVERE STORMS WILL
EXIST DURING THE AFTERNOON HOURS (ALTHOUGH COVERAGE WILL BE QUITE
ISOLD).

AND NOW FOR ROGERS LAST DISCUSSION AT FGF...

SATURDAY-TUESDAY...SATURDAY THROUGH TUESDAY NIGHT...MEDIUM-RANGE
MODELS IN GOOD AGREEMENT SHOWING EASTERN PACIFIC SHORT-WAVE
TRAVERSING THE FORECAST AREA SATURDAY FROM NORTHWEST TO SOUTHEAST
AND THEN BEING INGESTED INTO LARGER HUDSON BAY LOW ACROSS THE
GREAT LAKES. ASSOCIATED SFC LOW SKIRTS THE NORTHWEST ANGLE BEFORE
DIVING INTO THE MN ARROWHEAD. MAJORITY OF PRECIP REMAINS TO THE
NORTH OF THE LOW UNTIL SATURDAY NIGHT WHEN ITS COLD FRONT MOVES
ACROSS THE FORECAST AREA. WILL KEEP ALL BLEND CHANCE POPS SAT/SAT
NIGHT WITH DRYING FROM WEST TO EAST ON SUNDAY. MON/TUES LOOK
MOSTLY DRY AS SFC HIGH PRESSURE DRIFTS ACROSS THE NORTHERN PLAINS.
EXPECT LITTLE DAY TO DAY VARIATION IN TEMPS WITH HIGHS IN THE MID
70S TO LOWER 80S AND LOWS IN THE MID-50S.
