Area forecast discussion, Jun 21, 2:17 PM CDT, 3 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND FORKS ND
217 PM CDT THU JUN 21 2012

.SHORT TERM...

THE MAIN CHALLENGE WILL BE CONVECTION THROUGH THIS EVENING...THEN
SHOWERS AND STORMS LATE FRI NIGHT INTO SAT NIGHT. MODELS ARE
COMING AROUND TO A MORE NORTHERLY SOLUTION FOR SAT SYSTEM...AND
THE GFS WAS THE FIRST TO INDICATE THIS POTENTIAL. WILL LEAN
TOWARDS THE GFS SLIGHTLY FOR THIS REASON...BUT NO MAJOR
DIFFERENCES OVERALL.

FOR THE REST OF THIS AFTERNOON INTO THE EVENING...EXPECT SHOWERS
AND THUNDERSTORMS IN THE NORTH WITH A SHORTWAVE AND AMPLE
INSTABILITY/LIFT. CAN/T RULE OUT A FEW STORMS BECOMING MARGINALLY
SEVERE WITH HAIL AND WIND THE MAIN THREATS. DEEP LAYERED SHEAR
WILL ONLY BE AROUND 30KT IN THE NORTH...SO PULSE TYPE STORMS
SHOULD BE THE RULE. THE THREAT FOR CONVECTION WILL DIMINISH AFTER
SUNSET...ALTHOUGH A SHORTWAVE MOVING INTO THE NORTH AROUND 06Z
COULD HELP A FEW SHOWERS AND STORMS LINGER UNTIL THEN.

ON FRIDAY...A DRY DAY IS EXPECTED WITH RIDGING BUILDING IN AND
WARMER TEMPS ALOFT. THERE IS A VERY LOW CHANCE FOR SOME SHOWERS
AND STORMS IN THE FAR NORTHEAST...BUT FOR NOW WILL GO WITH A DRY
FORECAST WITH NO SHORTWAVE ENERGY TO SPEAK OF.

FOR FRI NIGHT...EXPECT MOISTURE TO INCREASE IN THE SOUTH WITH A
LLJ DEVELOPING. THERE WILL BE SOME ELEVATED CAPE AND PWATS RISING
OVER AN INCH BY 12Z SAT. WILL INCREASE SHOWER AND STORM CHANCES IN
THE SOUTH OVERNIGHT.

FOR SAT INTO SAT NIGHT...THERE WILL BE AN 850MB FRONT LIFTING INTO
THE AREA. THERE WILL ALSO BE A LARGE INCREASE IN DEEP LAYERED
MOISTURE WITH PWATS PROGGED AROUND 1.50 INCHES FOR ALL BUT THE FAR
NORTH. WILL MENTION SHOWER AND THUNDER CHANCES IN ALL AREAS WITH
THE BEST CHANCE IN THE SOUTH NEAR DEEPER INSTABILITY. CLOUDS MAY
ALSO LIMIT HEATING AND TEMPS MAY HAVE TROUBLE GETTING INTO THE
MID/UPPER 70S LIKE WE HAVE PROGGED.

ON SUNDAY...SFC HIGH PRESSURE BUILDS IN FROM CANADA AND IT WILL BE
A DRY AND MOSTLY SUNNY DAY WITH TEMPS NEAR TO SLIGHTLY BELOW
NORMAL.

.LONG TERM (SUN NITE THROUGH THURSDAY)...
GFS/ECMWF IN AGREEMENT IN THEIR DEPICTION OF NORTHWEST FLOW AT
BEGINNING OF EXTENDED PERIOD OVER THE FORECAST AREA. LONGWAVE RIDGE
WILL QUICKLY BUILD IN FROM HIGH PLAINS AND THIS FEATURE WILL
DOMINATE FOR A COUPLE OF DAYS BEFORE TRANSITIONING TO SOUTHWEST FLOW
BY WEDNESDAY. THIS IS REFLECTED IN FORECAST BY A DRY MON/TUE BEFORE
LOW POPS ARE INTRODUCED ON WEDNESDAY. SURFACE BOUNDARY LIKELY TO SWING
THROUGH DURING THIS TIME WITH WEAK HIGH PRESSURE IN ITS WAKE FOR
THURSDAY. TEMPS WILL RUN A FEW DEGREES ABOVE SEASONAL
AVERAGE...TYPICAL TO THIS PATTERN.

&&

.AVIATION...
GUSTY WEST TO NORTHWEST WINDS WILL DIMINISH AROUND SUNSET...AND REMAIN
LIGHT THROUGH FRIDAY AS HIGH PRESSURE MOVES INTO AREA. SEVERAL HOUR
PERIOD OF VCTS INDICATED AT NORTHERNMOST TAF SITES AS CONVECTIVE
ACTIVITY HAS ALREADY INITIATED FROM DEVILS LAKE THROUGH NORTHERN RED
RIVER VALLEY.

&&

.FGF WATCHES/WARNINGS/ADVISORIES...
ND...NONE.
MN...NONE.
