AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1007 AM EST SAT FEB 14 2015
.SYNOPSIS...
A STRONG COLD FRONT WILL CROSS THE AREA THIS AFTERNOON AND
EVENING...BRINGING AN ARCTIC BLAST THROUGH EARLY WEEK. HIGH
PRESSURE CROSSES THE AREA MONDAY. LOW PRESSURE IS EXPECTED TO
TRACK NORTHEAST ACROSS THE DEEP SOUTH MONDAY NIGHT...MOVING OFF
THE NORTH CAROLINA COAST TUESDAY NIGHT BEFORE TRACKING INTO THE
GULF OF MAINE WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
...HAZARDOUS WINTER CONDITIONS EXPECTED LATER TODAY INTO
TONIGHT...
STRONG COLD FRONT WILL MOVE ACROSS THE CWA DURING THE AFTERNOON
AND EARLY EVENING...PRODUCING NUMEROUS SNOW SHOWERS AND PERHAPS
SOME HEAVIER SQUALLS FOLLOWED BY VERY WINDY AND VERY COLD
CONDITIONS TONIGHT.
ALREADY HAVE SOME LIFT OCCURRING CLOSE TO THE MASON DIXON
LINE THIS MORNING...LIKELY LEADING TO FLURRIES OR EVEN LIGHT SNOW.
ANY ACCUMULATIONS HERE SHOULD BE LIGHT. SNOW SHOWERS HAVE ALSO
BECOME APPARENT OVER THE WESTERN SLOPES OF THE POTOMAC HIGHLANDS.
MUCH OF THE REST OF THE CWA WILL BE DRY THROUGH THE MORNING AND
PERHAPS EVEN EARLY AFTERNOON...BUT AS STRONG LIFT MOVES IN IN
ASSOCIATION WITH THE APPROACHING COLD FRONT AND SHORTWAVE ONE OR
MORE BANDS OF SNOW SHOWERS ARE EXPECTED TO SWEEP ACROSS THE CWA
MOST LIKELY IN THE 4PM TO 9PM TIME FRAME.
THESE SNOW SHOWERS PERHAPS ACCOMPANIED BY HEAVIER SQUALLS MAY POSE
A PARTICULARLY HAZARDOUS SITUATION LATER THIS AFTERNOON AND EARLY
EVENING. VISIBILITIES WILL LIKELY QUICKLY DROP IN SNOW
SHOWERS...PERHAPS DOWN TO 1/4SM-1/2SM MILE FOR A BRIEF TIME. WHILE
SNOW MAY NOT LAST VERY LONG IN ANY ONE LOCATION...A QUICK /I.E. 30
MINUTES LONG/ HALF INCH OR INCH OF ACCUMULATION COULD RESULT. IN
ADDITION...TEMPERATURES ARE LIKELY TO RAPIDLY FALL AND ICY
CONDITIONS DEVELOP.
WE ALREADY HAVE WINTER WEATHER ADVISORIES FOR NORTHEAST MARYLAND
WHERE WE THINK 1 TO 3 INCHES TOTAL WILL OCCUR AND ALONG THE
WESTERN SLOPES /SHORTWAVE AND THEN UPSLOPE/. IN BETWEEN THESE
AREAS AND FURTHER SOUTH...WE ARE NOT REACHING SNOW CRITERIA BUT
IT IS STILL IMPORTANT TO STRESS THE POTENTIAL FOR HAZARDOUS
CONDITIONS/IMPACT AS DESCRIBED IN THE PREVIOUS PARAGRAPH EVEN
THOUGH SNOW TOTALS WOULD BE BELOW ADVISORY CRITERIA.
DANGEROUS COLD AND WIND MOVES IN OVERNIGHT AND WIND/WIND CHILL
HEADLINES REMAIN AS IS FOR NOW.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
COLDEST AIR OF THE SEASON FOLLOWS COLD FRONT WITH VERY WINDY
CONDITIONS. HIGH WIND WARNING AND WIND CHILL WARNING FOR MANY
AREA...ADVISORIES ELSEWHERE. TIMING OF WARNINGS WERE BASED ON

THOSE. HEADLINE DECISIONS BASED ON GFS BASED MOSGUIDE WINDS AND
TEMPERATURES FROM MET/SREF BLEND. CRITERIA FOR WIND CHILL IS -25F
FOR NRN MD AND WEST FROM BLUE RIDGE...-20F EAST. HIGH WIND CRITERIA
IS 58 MPH (50 KNOTS). WIND CHILL HEADLINES GO UNTIL NOON WHEN AN

WIND HEADLINES DROP NOON OR 2PM SUNDAY...SHOULD COVER THE TIMEFRAME
OF WIND ADVISORY GUSTS.
OTHERWISE SATURDAY EVENING...SNOW TAPERS TO ISOLATED SHOWERS BEHIND
THE COLD FRONT FROM WEST TO EAST. CURRENT THOUGHT IS PRECIP END TIME
OF AROUND 7PM FOR INTERSTATE 95...9PM OR SO FOR THE WRN SHORE OF THE
BAY/SRN MD.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
SUNDAY NGT WL BE ESPECIALLY COLD AND DRY. I DON'T NRMLY ADDRESS
DWPTS IN THE DSCN....BUT WE ARE LOOKING AT DWPTS OF BTWN -5 AND
-15. I DID A QUICK CHECK OF LAST JAN/FEB DWPTS: AS WE ALL KNOW
LAST JAN/FEB HAD A LOT OF COLD AIR. IN 2014 DC AREA HAD LOWEST
DWPT READING OF -14 IN JAN...AND -11 IN FEB...BUT VALUES THIS LOW
HERE ARE FAIRLY RARE. STATIC ELECTRICITY WL BE HIGH.
AFTR THE XTRMLY STRONG WIND OF SUN THESE WL BE SLOW TO DIMINISH
SUN NGT. THIS WL LKLY LEAD TO MORE WIND CHILL ADVSORIES BEING
NEEDED. THERE IS A PTNL FOR RECORD LOW TEMPS TO BE REACHED - SEE
CLIMATE SXN BLO FOR NUMBERS.

LGTR WINDS.
THE EURO HAS BEEN PERFORMING WELL AS OF LATE - IT HAD TMRW'S STRONG

FATE OF AN AREA OF LOW PRES COMING FM THE GULF STATES MON NGT. THE
GFS HAS IT OVR GA TUE AFTN...TURNING NE NEAR ORF AND INTENSIFYING
TUE NGT AS IT TRACKS OVR CAPE COD. THE EURO KEEPS IT FURTHER S -
NEAR HAT AT 06Z WED...THEN TAKING A MORE EWD TRACK AND IMPACTING
ATLC CANADA. THE GFS SOLN WOULD BE MORE PROBLEMATIC FOR MID ALTC.
WE ARE CURRENTLY FCSTG A CHC OF SN TUE/TUE NGT...LKLY SE OF DC.
DEPENDING UPON EVENTUAL TRACK THESE MAY BE CHGD.
TEMPS RMNG WELL BLO NRML THRU THE END OF THE WK. HIGHS SHOULD BE
IN THE M40S/LOWS M20S IN MID FEB.

.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
REST OF THIS MORNING LOOKS DRY...SAVE FOR A FEW FLURRIES NEAR
MTN/BWI. MAIN IMPACT LOOKS TO BE LATE AFTERNOON/EARLY EVENING WITH
A STRONG COLD FRONT BRINGING SNOW SHOWERS/SQUALLS. RAPID DROP IN
VISIBILITIES ARE EXPECTED IN SNOW SHOWERS. SNOW WILL ALSO BECOME
WIND DRIVEN AS WINDS INCREASE WITH THE FRONTAL PASSAGE. WINDS
BECOME PARTICULARLY STRONG TONIGHT...WITH GUSTS NEAR 50 KT AT
TIMES. NW WINDS STAY STRONG/GUSTY ON SUNDAY.
GUSTY WINDS CONT SUN NGT. HIGH PRES OVR THE AREA MON. CLDS MAY

HIGH PRESSURE BUILDING INTO THE REGION SUNDAY WILL BRING AN ENHANCED
FIRE THREAT. NW WINDS WILL GUST BETWEEN 45 AND 55 MPH SUNDAY
MORNING...ONLY DECREASING TO 30 AND 40 MPH SUNDAY AFTN/EVENING.
THE HIGH WILL BRING A VERY COLD AND DRY AIRMASS...RESULTING IN RH
VALUES DROPPING INTO THE 20S ACROSS CENTRAL VA...30S IN
EASTERN/CENTRAL MD...AND 50S WEST OF THE BLUE RIDGE. THE LAST
COMPONENT OF CONCERN IS THE 10 HR FUEL MOISTURE...WHICH CURRENTLY
ARE FORECASTED TO BE JUST BELOW 10 PERCENT. WE'LL MONITOR THE
TREND AND COLLABORATE WITH STATE FIRE SUPERVISORS TO DETERMINE THE
NEED OF A STATEMENT OR WARNING FOR SUNDAY.
