AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EASTERN ND/GRAND FORKS ND
310 PM CDT TUE APR 27 2004
.SHORT TERM...
MAIN CONCERN IN THE EARLY PERIODS IS THE COLD FRONTAL PASSAGE ON
WED. MODELS ARE COMING CLOSER IN TIMING (GFS STILL A TAD SLOWER) BUT
STILL DIFFER A BIT ON HOW MUCH LOW LEVEL MOISTURE THE SYSTEM CAN TAP
INTO. GFS (TRADITIONALLY HIGHER) SHOWING SFC DEW POINTS IN THE 50S
ACROSS THE SOUTHEAST FA BY WED PM (TOO HIGH). WILL USE A MODEL BLEND
FOR THE FORECAST BUT LEAN TOWARD THE ETA.
TEMPS TOOK A WHILE WARMING THIS MORNING...BUT ARE ACTUALLY RISING A
FEW DEGREES HIGHER THAN EXPECTED. FAVORABLE WEST/SW WINDS HELPING TO
MIX DOWN VERY WARM TEMPS. SEEING SOME HIGH BASED RETURNS ON THE KMVX
88D PRETTY MUCH ALL OVER THE FA...SO WILL THROW IN SOME ISOLATED
EVENING SHOWERS. WITH THE WIND STAYING STEADY OVERNIGHT AND SOME
CLOUDS...NOT EXPECTING TEMPS TO FALL TOO FAR. THEREFORE WILL START
OUT WED AT LEAST 10-15 DEGREES WARMER THAN THIS MORNING...AND WITH
850 MB TEMPS EVEN A COUPLE DEGREES WARMER. HIGH TEMPS WED IN ADVANCE
OF THE COLD FRONT ARE A BIG CHALLENGE. MESOETA ACTUALLY VERIFIED
PRETTY WELL TODAY AND IS SHOWING 85F ACROSS THE SOUTH WED. THEREFORE
TOOK TEMPS UP A COUPLE DEGREES IN THE SOUTH...WHILE THE NORTHWEST FA
SEES THE LEAST RISE. MODELS SHOWING BEST AREA OF INSTABILITY IN THE
SOUTHEAST FA WED WITH SOME WEAK CAPE. SPC DID BACK UP THE SLIGHT
RISK AREA A SHADE (NOW CLOSER TO NORTHWEST MN FA AS WELL AS WEST
CENTRAL MN FA). MOISTURE IS A QUESTION MARK...WITH GULF CLOSED. ALSO
UPPER LEVEL SUPPORT IS LAGGING WELL BEHIND THE SFC FRONT. EVEN SO
THE FRONT HAS STRONG THERMODYNAMICS TO WORK WITH. COULD THEREFORE BE
SOME HIGH BASED CONVECTION WITH WIND/DOWNBURSTS AS THE MAIN THREAT.
STRONG COLD ADVECTION IN THE WAKE OF THE COLD FRONT...COULD ALSO MIX
IN SOME SNOW. THEREFORE KEPT THE RAIN/SNOW SHOWER MIX THAT PREVIOUS
SHIFT ADDED FOR WED NIGHT. WIND SPEEDS WILL HAVE TO BE WATCHED...AS
THERE COULD BE SOME ADVISORY CRITERIA SPEEDS MET SOMETIME LATE WED
AFTERNOON INTO EARLY WED EVENING. MADE FEW CHANGES TO THE REST OF
THE EARLY PERIODS. NEXT SHORT WAVE STILL ON TARGET FOR LATE THU
NIGHT/FRI IN THE CYCLONIC FLOW WHICH WILL BRING THE NEXT CHANCE OF
RAIN.
.LONG TERM...
MAJORITY OF LONG RANGE MODELS (UK/CAN/GFS) SEEM TO BE TRENDING TO
LESS AMPLIFICATION OF MID LEVEL PATTERN HEADING INTO UPCOMING WEEK.
UNTIL THEN TOUGH TO TIME IMPULSES DROPPING DOWN SHARP NORTHERLY
FLOW. GFS SOMEWHAT CONSISTENT WITH WAVE BRINGING CHANCE PCPN SUNDAY
NIGHT WITH NEXT MAIN WAVE LATER DAY SEVEN. WITH LESS AMPLIFICATION
TEMPERATURES MODERATE CLOSER TO AVERAGE AFT SUNDAY.
&&
.FIRE WEATHER...
WILL ISSUE A FIRE WEATHER WATCH FOR SOUTHEAST MN FA FOR WED. TEMPS
LOOK TO PUSH THE LOW TO MID 80S WITH MIN RELATIVE HUMIDITY VALUES
RIGHT AROUND 20 PERCENT. WIND SPEEDS MAY BE THE BIGGEST QUESTION
MARK...BUT ARE CLOSE.
&&
.FGF WATCHES/WARNINGS/ADVISORIES...
ND...NONE.
MN...FIRE WEATHER WATCH FOR GRANT...OTTER TAIL...BECKER...WADENA...
HUBBARD...SOUTH BELTRAMI AND SOUTH CLEARWATER FOR WED.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EASTERN NORTH DAKOTA...WEST CENTRAL AND NORTHWEST MINNESOTA. .DAY ONE...TODAY AND TONIGHT LOW RELATIVE HUMIDITIES WILL COMBINE WITH WINDS GUSTING OVER 20 MPH AT TIMES TODAY IN EASTERN NORTH DAKOTA. THIS IN COMBINATION WITH VERY DRY FUELS WILL CAUSE THE POTENTIAL FOR HAZARDOUS FIRE WEATHER CONDITIONS TODAY. FIRE WEATHER PLANNERS NEED TO STAY TUNED TO LATER STATEMENTS TODAY AND BE SURE TO MONITOR CURRENT WEATHER TRENDS. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORMS CONTAINING LARGE HAIL AND DAMAGING WINDS WEDNESDAY AFTERNOON AND EVENING.

IN ADDITION...VERY STRONG WINDS ARE POSSIBLE WITH THE COLD FRONT ACROSS THE ENTIRE REGION LATE WEDNESDAY AFTERNOON INTO THE OVERNIGHT HOURS.
