That is interesting.. perhaps its because the WF will be nearby and it has them riding along it?

Still, unless we can really surge the warm front north they will likely be in a more elevated instability environment around here. Today has the feel of a dreary showers and drizzly day with no severe - at least around these parts.

LWX is putting SOME

THUNDERSTORMS MAY PRODUCE DAMAGING WINDS AND LARGE HAIL THIS

AFTERNOON. in their zones in the 1030 AM update. Looks like it gets to Howard Cty in MD

I think the only places that don't have it in the wording now is Balto Co. Balto City and Harford. Anne Arundel has it as well.

Updated AFD as of 1045 AM from LWX

NEAR TERM /THROUGH TONIGHT/...

-- Changed Discussion --WARM FRONT CURRENTLY ACROSS THE SW PORTIONS OF THE FORECAST AREA

THIS MORNING. VISIBLE SATELLITE IMAGERY SHOWS ATMOSPHERE

BEGINNING TO MIX ACROSS THE SHENANDOAH VALLEY AND SOUTHERN POTOMAC

HIGHLANDS...WHILE ACROSS THE NE CWFA...A COOL WEDGE IN PLACE. SEVERE

THUNDERSTORMS WILL HAVE THE POTENTIAL TO PRODUCE LARGE HAIL AND

DAMAGING WIND GUSTS.

DIFFICULT TO SAY EXACTLY WHERE THE WARM FRONT WILL SET UP THIS

AFTERNOON. HOWEVER...DO THINK THE AREA MOST LIKELY FOR THE WARM

FRONT TO SET UP IS FROM NORTHWEST MARYLAND...THROUGH THE EASTERN

WEST VIRGINIA PANHANDLE DOWN THROUGH THE NORTHERN VIRGINIA

PIEDMONT. IN OTHER WORDS...CLOSELY ORIENTED NW TO SE ACROSS THE

CWFA. HAVE LARGE HAIL WORDING IN MOST OF THE ZONES THIS

AFTERNOON...EVEN A LITTLE FURTHER NORTH OF WHERE THE WARM FRONT

MAY SET UP. SURFACE BASED STORMS DO HAVE A GOOD CHANCE OF GOING

ELEVATED NORTH OF THE WARM FRONT...THUS THE POTENTIAL OF LARGE

HAIL WILL CONTINUE TO EXIST. IF THERE IS ONE AREA WHERE THE

CHANCES OF SEVERE WEATHER WILL BE THE LEAST...IT WILL BE ACROSS

NORTHEAST MARYLAND...INTO PORTIONS OF LOWER SOUTHERN MARYLAND.

Mainly for our WV people.. but perhaps some of this might translate to us later if we get lucky

MESOSCALE DISCUSSION 0255

NWS STORM PREDICTION CENTER NORMAN OK

1102 AM CDT WED MAR 23 2011

AREAS AFFECTED...CNTRL-ERN KY...ERN IND...OH...WV

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 231602Z - 231730Z

A SEVERE THREAT WILL LIKELY DEVELOP ACROSS ERN IND...CNTRL-ERN

KY...OH AND WV THIS AFTERNOON. LARGE HAIL...WIND DAMAGE AND AN

ISOLATED TORNADO THREAT WILL BE LIKELY AS STORMS INITIATE AND EXPAND

QUICKLY IN COVERAGE. A TORNADO WATCH SHOULD BE NECESSARY OVER THE 1

TO 2 HOURS.

LATEST SFC ANALYSIS SHOWS A 998 MB LOW NEAR INDIANAPOLIS WITH A

QUASI-STATIONARY FRONT EXTENDING EWD ACROSS CNTRL OH. SOUTH OF THIS

BOUNDARY...MLCAPE VALUES ARE ESTIMATED IN THE 250 TO 1000 J/KG RANGE

FROM WV WWD ACROSS KY INTO SRN IND WHERE A LARGE AREA OF MODERATE

INSTABILITY SHOULD BE IN PLACE BY EARLY AFTERNOON. CONVECTIVE

INITIATION APPEARS LIKELY JUST AHEAD OF THE SFC LOW AND NEAR THE

STRONGEST INSTABILITY IN ERN IND...SW OH AND NCNTRL KY BY 18Z WHICH

THE 14Z HRRR AGREES WITH. RAPID DESTABILIZATION COMBINED WITH STRONG

DEEP LAYER SHEAR ASSOCIATED WITH A 75 TO 85 KT MID-LEVEL JET

EJECTING ENEWD OUT OF THE MID-MS VALLEY SHOULD BE VERY FAVORABLE FOR

SEVERE STORMS. THE STEEP MID-LEVEL LAPSE RATES ALREADY IN PLACE

SHOULD SUPPORT A LARGE HAIL THREAT WITH DISCRETE ROTATING STORMS.

WIND DAMAGE WILL ALSO BE POSSIBLE WITH THE MORE INTENSE STORMS

ESPECIALLY DUE TO THE FAST EWD STORM MOTIONS. LOW-LEVEL SHEAR WILL

ALSO BE SUPPORTIVE OF A TORNADO THREAT ESPECIALLY WITH THE MORE

DOMINANT SUPERCELLS.

Well if the sun comes back out after this batch of showers, it will set the stage. Timing looks good for max heating.

URGENT - IMMEDIATE BROADCAST REQUESTED

TORNADO WATCH NUMBER 55

NWS STORM PREDICTION CENTER NORMAN OK

115 PM EDT WED MAR 23 2011

THE NWS STORM PREDICTION CENTER HAS ISSUED A

TORNADO WATCH FOR PORTIONS OF

SOUTHERN AND EASTERN INDIANA

MUCH OF KENTUCKY

EXTREME WESTERN MARYLAND

CENTRAL AND SOUTHERN OHIO

SOUTHWEST PENNSYLVANIA

FAR WESTERN VIRGINIA

MUCH OF WEST VIRGINIA

EFFECTIVE THIS WEDNESDAY AFTERNOON AND EVENING FROM 115 PM UNTIL

900 PM EDT.

TORNADOES...HAIL TO 2.5 INCHES IN DIAMETER...THUNDERSTORM WIND

GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE

AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 160 STATUTE

MILES EAST AND WEST OF A LINE FROM 40 MILES NORTH NORTHEAST OF

ZANESVILLE OHIO TO 60 MILES EAST SOUTHEAST OF BOWLING GREEN

KENTUCKY. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE

ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU5).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR

TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH

AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR

THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS

AND POSSIBLE WARNINGS.

DISCUSSION...ALONG AND ESPECIALLY AHEAD OF A COLD FRONT...MULTIPLE

BROKEN BANDS OF STRONG/SEVERE TSTMS WILL DEVELOP THROUGH THE

AFTERNOON. GIVEN MODEST INSTABILITY/STEEP LAPSE RATES ALOFT COUPLED

WITH VERY STRONG VERTICAL SHEAR...THE DEVELOPMENT OF BOTH

SEMI-DISCRETE/SPLITTING SUPERCELLS AND BOWS ARE PROBABLE. LARGE HAIL

AND DAMAGING WINDS ARE THE PRIMARY CONCERNS...BUT A FEW TORNADOES

WILL BE POSSIBLE AS WELL GIVEN THE DEGREE OF LOW LEVEL SPEED SHEAR.
