SYNOPSIS
THE FORECAST REGION WILL BE AHEAD OF AN APPROACHING COLD FRONT.
THIS COLD FRONT MOVES ACROSS LATE TONIGHT. THEN, STRONG LOW
PRESSURE REMAINS NORTH OF THE REGION WITH HIGH PRESSURE
REMAINING WELL SOUTHWEST OF THE REGION FOR LATE THIS WEEK
HEADING INTO THE START OF THE WEEKEND. FOR SATURDAY INTO
SATURDAY NIGHT, THE HIGH PRESSURE AREA EVENTUALLY BUILDS INTO
THE AREA, FOLLOWED BY THE DEPARTURE OF THIS HIGH PRESSURE
OFFSHORE ON SUNDAY. MEANWHILE ANOTHER LOW PRESSURE SYSTEM WILL
BE MOVING INTO THE GREAT LAKES WHICH WILL PASS TO THE NORTH AND
EAST EARLY NEXT WEEK.
NEAR TERM /THROUGH TONIGHT/
THERE WILL BE AN APPROACHING MID AND UPPER LEVEL TROUGH. THE
ASSOCIATED JET STREAK WILL BE MOVING ACROSS THE LOCAL REGION FOR
TONIGHT. AT THE SURFACE, THE LOCAL REGION WILL BECOME MORE
ENCOMPASSED WITHIN THE WARM SECTOR OF THE APPROACHING FRONTAL
SYSTEM. ITS ASSOCIATED COLD FRONT WILL BE APPROACHING THE LOCAL
AREA. WITH THE SOUTHWEST FLOW AND MOISTURE LADEN BOUNDARY LAYER,
PATCHY FOG WILL LINGER AROUND THE REGION.
THIS COLD FRONT MOVES ACROSS FROM WEST TO EAST LATE TONIGHT. THE
COLD FRONT WILL BE STRONG WITH LOW TO MID LEVEL FRONTOGENESIS
INCREASING DURING THIS SAME TIMEFRAME. STRONG COLD AIR ADVECTION
SEEN WITH THE RAPID DECREASE OF TEMPERATURES AT 850MB. THIS WILL
INCREASING THE BOUNDARY LAYER AND ALLOW FOR GUSTY WESTERLY FLOW TO
BECOME MORE FREQUENT AND COMMON ACROSS THE REGION.
REGARDING PRECIPITATION, THERE WILL BE POTENTIAL FOR ADDITIONAL RAIN
SHOWERS FROM THE INCREASING LIFT AND DIVERGENCE ALOFT. DRYING
CONDITIONS WILL TAKE PLACE LATE TONIGHT WITH THAT STRONG COLD AIR
ADVECTION AS DEWPOINTS LOWER SIGNIFICANTLY ALSO.
SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
KEY POINTS
* WINDS OF NEAR 20 MPH WITH GUSTS NEAR 35 TO 40 MPH FORECAST FOR
THANKSGIVING. HIGH TEMPERATURES THANKSGIVING MAINLY LOW TO MID 40S
BUT WIND CHILLS STAY IN THE 30S.
* WINDS OF NEAR 25 MPH WITH GUSTS NEAR 40 TO 45 MPH FORECAST FOR
FRIDAY. THERE IS STILL SOME MODEL INDICATION OF NEAR 50 MPH
WIND GUSTS BEING POSSIBLE. HIGH TEMPERATURES FRIDAY MAINLY IN
THE UPPER 30S TO LOWER 40S WITH WIND CHILLS STAYING MOSTLY IN
THE 20S TO LOWER 30S.
THE KEY POINTS WITH THE SHORT TERM WILL BE GUSTY WINDS AND WITH THE
HIGHER WINDS, COLD TEMPERATURES AS WELL AS WIND CHILLS. NO
MEASURABLE PRECIPITATION IS EXPECTED DURING THE TIMEFRAME OF
THANKSGIVING THROUGH FRIDAY NIGHT. THERE COULD BE A FEW LIGHT
RAIN/SNOW SHOWERS WITH STRONG MID LEVEL VORTICITY MAXIMUM
PUSHING ACROSS ON FRIDAY. A MUCH COLDER AIRMASS WILL BE ACROSS
THE REGION DURING THE SHORT TERM.
MID AND UPPER LEVEL TROUGH MOVE INTO THE REGION THANKSGIVING INTO
FRIDAY WITH UPPER LEVEL JET MOVING SOUTH OF THE REGION. THE MID AND
UPPER LEVEL FLOW BECOME LESS AMPLIFIED FRIDAY NIGHT WITH THAT
FLATTENING OF THE FLOW, RETURNING TO NEARLY ZONAL. AT THE SURFACE,
PARENT LOW PRESSURE MOVES EASTWARD WITHIN QUEBEC. HIGH PRESSURE
REMAINS WELL SOUTH AND WEST OF THE REGION. MODEL GUIDANCE INDICATES
SLIGHT RISING PRESSURE MAGNITUDE OF THE PARENT LOW AND LOWERING OF
THE HIGH PRESSURE MAGNITUDE. STILL A STEEP PRESSURE GRADIENT IS
EXPECTED BUT THE PEAK WIND GUSTS ARE STILL A FORECAST PARAMETER WITH
ASSOCIATED LOW CONFIDENCE. MAINTAINED CONTINUITY WITH PREVIOUS
FORECAST, SHOWING HOW FRIDAY WILL BE TIGHTER PRESSURE GRADIENT AND
HIGHER WINDS AND GUSTS COMPARED TO THURSDAY.
DEEP VERTICAL MIXING IS STILL EXPECTED FRIDAY TO AROUND 7 TO
8KFT. WHILE NBM IS INDICATING VERY LOW PROBABILITIES OF WIND
GUSTS EXCEEDING 45 MPH, THE NBM HAS RECENTLY UNDER-PREDICTED
WIND GUSTS AND STILL EXHIBITS THIS BIAS FOR PARTS OF THE CENTRAL
US WITH THEIR CURRENT SYSTEM, WHICH WILL ACTUALLY BE THE SAME
SYSTEM THAT PASSES TO THE NORTH OF THE LOCAL AREA TOWARDS THE
END OF THIS WEEK. GFS BUFKIT AND NAM BUFKIT BOTH SHOW TOP OF
MIXED LAYER FOR A FEW LOCATIONS WITH WINDS NEAR 40-45 KT AND THE
GFS BUFKIT HAS BEEN SHOWING THIS A FEW TIMES WITH MULTIPLE
MODEL RUNS FOR FRIDAY. ON A WESTERLY FLOW, EFFICIENT VERTICAL
MIXING AND WINDS NEAR THE TOP OF THE MIXED LAYER CAN MORE EASILY
BE BROUGHT DOWN TO THE SURFACE.
LONG TERM /SATURDAY THROUGH TUESDAY/
NBM FOLLOWED WITH SOME SLIGHT ADJUSTMENTS TO TEMPERATURE SUNDAY
NIGHT. PREVIOUS DISCUSSION FOLLOWS.
