CranberryWX Posted January 26, 2011 Share Posted January 26, 2011 First line of precip is about 50 miles south of me. Currently 40/36 after a high of 48. I expect this to be rain event for a while in my back yard. Link to comment Share on other sites More sharing options...

dobie Posted January 26, 2011 Share Posted January 26, 2011 34/24 in S/E Fairfax Station. I'm excited that temps have dropped this low at this point. I think we're going to a warning by 11pm. This storm is getting mean on Fla. with tornado warnings and a HUGE line of thunderstorms. Setting records for rainfall in Jacksonville and other cities down south. This is all good news for us. However, the second upper level low could be our best friend! I hate to say it and don't want to believe it, but we may start out as a cold rain until cooling kicks in. The heaviest snow should start early afternoon (I'm looking at 1pm) and continue through 8-10pm. Let's collectively call out this storm to save us from the snowlessness so far this year!!

ThePhotoGuy Posted January 26, 2011 Share Posted January 26, 2011 .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... -- Changed Discussion --NO ADDITIONAL HEADLINE CHANGES ARE EXPECTED THIS EVENING. WE UPGRADED WEST OF THE BLUE RIDGE TO A WINTER STORM WARNING EARLIER THIS EVENING DUE TO INCREASED CONFIDENCE IN 5 OR MORE INCHES OF SNOW IN A 12 HOUR PERIOD. GENERALLY WENT WITH 4 TO 8 INCH SNOWFALL ACCUMULATIONS IN THIS AREA. THERE COULD BE A LITTLE SLEET OR FREEZING RAIN THAT MIXES IN AT THE ONSET. AREAS EAST OF THE BLUE RIDGE REMAIN IN A WINTER STORM WATCH AS CONFIDENCE IN WARNING CRITERIA IS A LITTLE LOWER. THIS IS LARGELY DUE TO THE LOCATION OF THE RAIN/SNOW LINE...WHICH WILL ULTIMATELY DETERMINE SNOWFALL ACCUMULATIONS. THERE IS STILL THE POTENTIAL FOR 5 OR MORE INCHES WITHIN THE WATCH AREA AS WELL...BUT WE JUST DONT HAVE THE CONFIDENCE TO UPGRADE TO A WARNING RIGHT NOW. HOPEFULLY 00Z GUIDANCE WILL OFFER INCREASED CONFIDENCE WHERE THE RAIN/SNOW LINE WILL SET UP AND THEN HEADLINE ADJUSTMENTS CAN BE MADE OVERNIGHT. WE ARE ALREADY WATCHING AN INITIAL BAND OF PRECIPITATION APPROACH FROM SOUTHWEST VIRGINIA THIS EVENING. THIS WILL MOVE INTO THE CENTRAL VIRGINIA FOOTHILLS/CENTRAL SHENANDOAH VALLEY LATE THIS EVENING...MOST LIKELY IN THE FORM OF RAIN. FURTHER NORTH OVERNIGHT IT MAY BE IN THE FORM OF A LIGHT WINTRY MIX...BUT OBVIOUSLY THE BULK OF THE PRECIPITATION IS EXPECTED ON WEDNESDAY AND THAT IS WHEN WE EXPECT THE MOST IMPACT FROM THE WEATHER.-- End Changed Discussion -- && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... -- Changed Discussion --ANY RAIN/SNOW MIX WEST OF THE BLUE RIDGE TO START WILL TRANSITION TO SNOW DURING THE MORNING AS THE WINTER STORM WARNING GOES INTO EFFECT. ALL SNOW WILL BE DELAYED EAST OF THE BLUE RIDGE...ESPECIALLY ALONG INTERSTATE 95 AND TO THE SOUTHEAST OF THERE. BUT WHEN IT DOES SNOW...IT MAY COME DOWN FAIRLY HARD FOR A PERIOD OF TIME. WE WILL NEED TO FINE TUNE WHERE THE RAIN/SNOW LINE SETS UP. BASED ON THE LATEST MODEL DATA...AM BECOMING INCREASINGLY CONVINCED OF A COLDER SOLUTION WHICH WOULD FAVOR HEAVY SNOWFALL ACCUMULATIONS FURTHER EAST. WILL HAVE TO SEE IF 00Z GUIDANCE CONTINUES TO SUPPORT THIS IDEA. OBVIOUSLY A SMALL CHANGE IN THE RAIN/SNOW LINE CAN HAVE A LARGE IMPACT REGARDING SNOWFALL TOTALS OVER THE BALTIMORE/WASHINGTON AREA. IN ADDITION...THIS STORM WILL LIKELY EXHIBIT BANDING CHARACTERISTICS AND WE/LL HAVE TO TRY TO PINPOINT WHERE BANDING OCCURS WHICH WILL ENHANCE SNOWFALL ACCUMULATIONS. EITHER WAY...FOLKS SHOULD BE PREPARED FOR SIGNIFICANT IMPACT DURING THE AFTERNOON AND EVENING RUSH HOUR DUE TO SNOW. SNOW WILL END FROM SOUTHWEST TO NORTHEAST AS A DRY SLOT ADVANCES THROUGH THE CWA LATER IN THE EVENING AND OVERNIGHT HOURS.-- End Changed Discussion -- Link to comment Share on other sites More sharing options...

Yeoman Posted January 26, 2011 Share Posted January 26, 2011 Pretty impressive line of storms rolling through Florida. Based on radar progress this initial batch should be in around 1-2am.. probably a lull through mid-morning leading to the big thump. Link to comment Share on other sites More sharing options...
