ATTENTION FOCUSED ON THE COLD TEMPERATURES EXPECTED TONIGHT. WITH
LIGHT WINDS AND THE EARLY START TO ALL THE VEGETATION THIS SPRING...
WILL GO AHEAD AND PUT OUT A FROST ADVISORY.  MAY BE MORE PATCHY IN
NATURE ALONG THE RIVER COUNTIES...BUT STILL FEEL AN ADVISORY IS

.PREV DISCUSSION...

SHORT TERM...TODAY THROUGH THURSDAY NIGHT

FORECAST CONCERNS THIS PACKAGE...COLD TEMPS/FROST POTENTIAL
TONIGHT...FIRE WEATHER CONCERNS WED...STRONG WINDS THU...
SHRA/TSRA CHANCES THU/THU NIGHT.

DATA ANALYSIS AT 06Z HAD LOW PRESSURE OFF THE NJ/MD COAST WITH
TROUGHING TO THE WEST ACROSS THE OH VALLEY THEN NORTHWEST ACROSS
IL/IA/MN TO NEAR LK WINNIPEG. THE TROUGH WAS SLOWLY SINKING SOUTH
ACROSS THE REGION...WITH HIGH PRESSURE BUILDING SOUTH FROM WESTERN
ONT. WV IMAGERY SHOWED A SHORTWAVE AND UPPER LOW OVER MO...TRACKING
SOUTHEAST. SCT -SHRA OVER IA WITH THESE FEATURES SLOWLY WANING AND
SHIFTING TO THE SOUTH...AS WERE THE CLOUDS OVER MUCH OF THE REGION.
GRADIENT WINDS IN THE 5 TO 15KT RANGE KEEPING THE BOUNDARY LAYER
STIRRED THIS MORNING...AND TEMPS WARMER THAN EXPECTED...ESPECIALLY
OVER THE NORTHEAST END OF THE FCST AREA WERE THE FROST ADVISORY IS
IN EFFECT. TEMPS ACROSS THE FCST AREA STILL IN THE 40S TO LOW 50S AS
OF 07Z.

27.00Z MODEL INITIALIZATIONS ALL LOOK QUITE GOOD...BUT FOR ALL TOO
HIGH WITH SFC DEW POINTS OVER THE NORTH CENTRAL CONUS...ESPECIALLY
WITH THE DRY AIR OVER NORTHERN WI. SOLUTIONS IN REASONABLY GOOD
AGREEMENT THRU WED NIGHT BEFORE DIVERGING WITH THE HANDLING OF THE
STRONG TROUGHING INTO THE CENTRAL CONUS AND RESULTING LOW/COLD FRONT
TO IMPACT THE AREA LATER IN THE WEEK. DPROG/DT OF 500MB HGTS AT
27.00Z SHOWED MODEL RUNS OF 25.00Z AND 26.00Z VERIFIED WELL WITH
GOOD CONSISTENCY WITH THE EASTERN PAC TROUGH. MODELS CONVERGED
TOWARD A CONSENSUS OF EARLIER RUNS WITH THE SOUTHWEST IA UPPER
LOW...WITH ECMWF OFFERING THE BETTER RUN-TO-RUN CONSISTENCY. THRU
36HRS MODELS CONVERGING TOWARD THE SLOWER/STRONGER OF THE EARLIER
SOLUTIONS WITH THE TROUGH/UPPER LOW OVER THE NORTHEAST CONUS. MODEL
CONSENSUS BETTER WITH THE WESTERN CONUS TROUGH. ECMWF WITH THE
BETTER RUN-TO-RUN CONSISTENCY AT 36HRS. MODELS SLOWLY CONVERGING
TOWARD A COMMON SOLUTION THRU 36 TO 60HRS. OVERALL TREND FAVORS
SLOWER OF EARLIER RUNS...WITH AGAIN ECMWF SHOWING THE BETTER RUN-TO-
RUN CONSISTENCY. MODELS CONTINUE TO SLOWLY CONVERGE TOWARD A COMMON
SOLUTION IN THE 60-84HR TIME-FRAME...WITH THE OVERALL SLOWING TREND
STILL FAVORED. GFS APPEARS AS A BIT OF A FAST OUTLIER AT 84HRS...
WITH ECMWF SHOWING THE BETTER CONSISTENCY. CHECK OF OBS VS. MODEL
DATA AT 06Z SHOWED MODELS QUITE REASONABLE WITH THE SFC MASS FIELDS
ACROSS THE CENTRAL CONUS...EVEN REASONABLY CAPTURING THE LOW DEW
POINTS/DRY AIR OVER NORTHERN WI. GEM/NAM/ECMWF BETTER THAN GFS WITH
00Z-06Z PRECIP ACROSS THE REGION. PER WV IMAGERY ALL MODELS APPEAR
GOOD WITH THE SHORTWAVE DETAILS ACROSS NOAM/EASTERN PAC. OVERALL
FAVORED THE MODEL/ENSEMBLE CONSENSUS...WEIGHTED TOWARD THE ECMWF
WITH ITS BETTER RUN-TO-RUN CONSISTENCY. FCST CONFIDENCE THIS CYCLE
GOOD THRU WED NIGHT THEN DECREASES FOR THU/THU NIGHT WITH THE
PERSISTENT MODEL STRENGTH/TIMING DIFFERENCES WITH SFC FEATURES.

FOR THE SHORT TERM...FIRST CONCERN IS THE FROST ADVISORY. GRADIENT
WINDS/BOUNDARY LAYER MIXING WINNING OUT THIS MORNING...WITH 3 AM
TEMPS IN THE ADVISORY AREA STILL MOSTLY IN THE LOW-MID 40S. WITH
THE GRADIENT WINDS/MIXING TO CONTINUE THRU SUNRISE...WILL CANCEL THE
FROST ADVISORY WITH THE 4 AM PACKAGE. DRY HIGH PRESSURE SETTLES
ACROSS THE REGION FOR TODAY/TONIGHT INTO WED. DRY AIRMASS...WITH
DEW POINTS IN THE MID TEENS AND 20S WILL BE OVER THE AREA TODAY...
WITH GENERALLY SMALL DEW POINT RECOVERY TONIGHT. WINDS TO BE
LIGHT/VARIABLE TONIGHT WITH THE SFC RIDGE AXIS OVER THE AREA...
ESPECIALLY THE NORMAL COOLER EASTERN PARTS OF THE FCST AREA.
GRADIENT TIGHTENS A BIT OVER THE WEST HALF OF THE FCST AREA AFTER
MIDNIGHT TONIGHT AS THE RIDGE AXIS SHIFTS EAST AND LOW PRESSURE
STRENGTHENS IN THE LEE OF THE ROCKIES. WILL LIKELY NEED A FROST
ADVISORY TONIGHT EAST OF THE MS RIVER...BUT WILL LET DAY CREW WATCH
TRENDS TODAY AND FINE-TUNE THE ADVISORY ISSUANCE WITH THE AFTERNOON
PACKAGE. GRADIENT OVER THE AREA TIGHTENS FOR WED THRU THU THE LOW
CONTINUES TO STRENGTHEN IN THE WESTERN PLAINS INTO SASKAT...THEN
MOVES TOWARD WESTERN MN ON THU. MODEL CONSENSUS INDICATES DEW
POINTS SLOW TO RECOVER ON WED...RESULTING IN MINIMUM AFTERNOON
HUMIDITIES IN THE 18-28 PERCENT RANGE. THIS ALONG WITH THE
INCREASING SOUTH WINDS MAY POSE SOME FIRE WEATHER CONCERNS ON WED...
DEPENDING ON HOW QUICKLY/MUCH THE SFC WINDS INCREASE BY THE
AFTERNOON. EARLIER MODEL SIGNAL OF A STRONGER 850-700MB MOISTURE
TRANSPORT/THETA-E CONVERGENCE/WARM ADVECTION OVER THE AREA LATE WED
NIGHT/THU MORNING HAS WEAKENED OR SHIFTED WEST OF THE AREA WITH THE
OVERALL MODEL SLOWING TREND. MODEL SOUNDINGS STABLE THRU 500MB...
WITH SOUNDINGS INDICATING ANY SATURATION BY 12Z THU AT OR ABOVE
600MB. GIVEN THIS...REMOVED THE SMALL -TSRA CHANCE FROM LATE WED
NIGHT AND LOWERED SHRA/TSRA CHANCES FOR THU MORNING. MODEL SOUNDINGS
INDICATE A RATHER STRONG INVERSION IN THE 850-750MB LAYER OVER THE
AREA THU...WITH UPWARDS OF 200 J/KG OF CIN IN THE 750-600MB LAYER.
LOWERED RAIN CHANCES FOR THU AFTERNOON AS WELL...AND MAY YET BE ABLE
TO REMOVE THE RAIN CHANCES FROM THU IF THE STRONG INVERSION/CAP AND
MINIMAL FORCING/LIFT PROVES CORRECT. A WINDY DAY THU WITH THE
TIGHTEST PRESSURE GRADIENT OVER THE AREA...MAY YET NEED A WIND
ADVISORY FOR THE MORE WIND-PRONE WESTERN PORTIONS OF THE FCST AREA
ON THU. DEW POINTS TO BE INCREASING THU IN THE SOUTHERLY FLOW.
MOISTURE TRANSPORT/THETA-E CONVERGENCE...HGT FALLS/LIFT ALOFT AHEAD
OF THE ADVANCING LOW/UPPER TROUGH INCREASE THU NIGHT. MU CAPE ON THE
ORDER OF 250-750 J/KG SPREADS INTO THE AREA AS WELL AHEAD OF THE
PLAINS LOW/TROUGH. FAVORING THE MODEL/ENSEMBLE CONSENSUS...RAISED
SHRA/TSRA CHANCE TOWARD OR TO LIKELY FOR MUCH OF THE FCST AREA BY
LATE THU NIGHT.

NUMERICAL TEMP GUIDANCE QUITE SIMILAR FOR TODAY THRU THU NIGHT AND
LOOK QUITE REASONABLE FOR MOST PERIODS. LOWS WED NIGHT WITH THE
BRISK SOUTH GRADIENT WINDS/WARM ADVECTION MAY BE TOO COOL...BUT
BLEND WELL WITH NEIGHBORING GRIDS FOR NOW.

.LONG TERM...FRIDAY THROUGH MONDAY

27.00Z MEDIUM RANGE MODELS ALREADY AT ODDS WITH TIMING/STRENGTH OF
THE SFC LOW/COLD FRONT AT THE START OF THE LONG-TERM PERIOD...WITH
LONG-TERM FCST CONFIDENCE GENERALLY ON THE LOW SIDE. MODEL/ENSEMBLE
CONSENSUS HAS THE DEEPEST MOISTURE...STRONGEST MOISTURE TRANSPORT/
FORCING/LIFT ACROSS THE AREA FRI...AND RAISED SHRA/TSRA CHANCE TO
LIKELY FOR FRI. DEPENDING ON TIMING AND HOW MUCH CAPE MAY BUILD
AHEAD OF THE ACTUAL COLD FRONT...MAY BE A SEVERE RISK WITH ANY
STORMS ON FRI. IF THE MODEL CONSENSUS IS GOOD FOR FRI...AND AREA
COVERED BY CLOUDS AND SCT SHRA/TSRA AROUND THE AREA...FRI HIGHS MAY
BE AS MUCH AS 5F TO 10F TOO HIGH. LEFT THESE AS IS FOR NOW WITH THE
FRONTAL TIMING UNCERTAINTIES. ONCE THE FRONT SWEEPS THRU...APPEARS
SOME DRIER WESTERLY LOW-MID LEVEL FLOW IS OVER THE AREA FOR AT LEAST
A PORTION OF THE WEEKEND. WILL LEAVE IT TO DAY CREW...BUT APPEARS
SHRA/TSRA CHANCES FOR SAT INTO SUN COULD BE LOWERED OR REMOVED IF
LATEST MODEL CONSENSUS IS CORRECT. SHRA/TSRA CHANCE MON APPEARS
REASONABLE WITH SOME CONSENSUS AMONG GFS/ECMWF FOR ANOTHER SHORTWAVE
TROUGH TO BE MOVING ACROSS THE REGION.

.AVIATION...TODAY AND TONIGHT

A RIDGE OF HIGH PRESSURE OVER NORTHERN ONTARIO WILL BUILD INTO THE
TAF SITES THIS AFTERNOON...THEN DRIFT OFF TO THE EAST TONIGHT.
EXPECT VFR CONDITIONS TO CONTINUE THROUGH TONIGHT THANKS TO DRY AIR

DIMINISH BELOW 10 KNOTS THIS MORNING AS THE RIDGE MOVES IN...AND
REMAIN BELOW 10 KNOTS THROUGH TONIGHT..AVIATION...
