After some moderate to heavy rain on the night of the 17th, cold air quickly came in and freezed the remaining rain drops on cars parked along North 29th Street.
It looks like another small system will being pushing through Central Virginia tomorrow morning into the early afternoon hours. The NWS has the following information:
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
QUICK UPDATE TO ACCOUNT FOR SHRAS ALONG THE FRONTAL BAND, WHICH HAVE
GENERALLY DIMINISHED...LEAVING ONLY SOME PATCHY LIGHT RAIN/DZ
ACROSS SE TIER OF COUNTIES. MEANWHILE, SOME MID/UPPER DRYING HAS
ENTERED EASTERN WV/WESTERN VA HAS ALLOWED FOR SOME AREAS OF FOG
OVER THE PIEDMONT...PRIMARILY WHERE CAD WEDGE WAS STRONGEST OVER
THE WEEKEND.
DID SLOW ONSET OF POP SLIGHTLY ACROSS OUR MD ZONES. OVERALL,
MUCH OF PREVIOUS FORECAST REMAINS UNCHANGED. LATER TONIGHT...A
VIGOROUS TROUGH (PRESENTLY DIVING SE ACROSS THE NORTHERN PLAINS)
WILL REACH THE MIDWEST. THIS WILL ALLOW -RA TO RE-DEVELOP ALONG
THE MOIST FRONTAL BAND AS IT LIFTS BACK NORTHWARD. ACCORDINGLY, WL
SHOW INCREASE IN POP LATE ACROSS MOST OF THE AREA (ASIDE FROM THE
LOWER MD EASTERN SHORE) LATER TONIGHT. TEMPERATURES SHOULD REMAIN
STEADY IN THE MID/UPPER 40S SE OVERNIGHT...WHILE LOWS SHOULD REACH
THE LOW/MID 30S NW WITH SHORT LIVED CLEARING.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
THE AFOREMENTIONED TROUGH GENERATES A POWERFUL 180KT (GEOSTROPHIC
WIND) 300MB JET...THAT RACES ENE ACROSS THE OHIO VALLEY TUESDAY
MORNING. THIS INDUCES A BAND OF STRONG FRONTOGENESIS ACROSS THE MID
ATLANTIC TUESDAY MORNING ALONG WITH ROBUST UPWARD VERTICAL MOTION.
ADDITIONALLY...THERE IS DECENT MOISTUREADVECTION AHEAD OF THE
TROUGH. MODEL CROSS-SECTIONS (NAM/GFS) INDICATE A RATHER CLASSIC
SLOPING FRONTAL ZONE WITH STRONG FRONTOGENESIS FROM THE SURFACE TO
AROUND 600MB. IN ADDITION...MODESTLY NEGATIVE EPV VALUES AND
NEUTRAL THETA-E LAPSE RATES INDICATE A POTENTIAL FOR SYMMETRIC
INSTABILITY. ALL THIS COMBINED SUPPORTS THE POTENTIAL FOR HEAVY
BANDED PRECIPITATION ACROSS THE MID-ATLANTIC REGION.
AT THIS TIME...THE STRONGEST BAND APPEARS TO SET-UP NEAR THE FAR
NORTHERN PORTION OF THE AKQ CWA. GIVEN THE STRENGTH OF THE
SYSTEM...THERE SHOULD BE LITTLE DIFFICULTY CHANGING THE PRECIP OVER
TO SNOW (DRIVING SURFACE TEMPS DOWN TO THE WET-BULB...WHICH WL BE
~ 30-32F)...BUT THERE COULD BE A MIX WITH SLEET EARLY DUE TO
RESIDUAL MID-LEVEL WARM AIR. SNOW AMOUNTS SHOULD RANGE FROM 1-3IN
ACROSS THE FAR N (LOCALIZED AMOUNTS AROUND 4 ARE POSSIBLE)...AND
TAPERING TO AN INCH OR LESS IN VICINITY OF A LINE FROM FVX-RIC-
WAL. AN ADVISORY HAS BEEN RAISED FOR THE NORTHERN PORTION OF THE
AREA.
DRIER AIR QUICKLY COMES IN FROM THE WEST DURING THE AFTERNOON AND
THIS SHOULD BRING A QUICK END TO PRECIPITATION. HIGH PRESSURE
FINALLY BUILDS IN FROM THE NW TUESDAY NIGHT INTO THURSDAY BRINGING
DRIER BUT VERY COLD CONDITIONS. LOWS TUESDAY/WEDNESDAY NIGHT SHOULD
RANGE FROM THE UPPER TEENS TO LOW 20S NW...TO THE LOW 30S NC
COAST...WITH HIGHS WEDNESDAY/THURSDAY ONLY IN THE UPPER 30S TO LOWER
40S FOR MOST AREAS.

A complex storm system is shaping up for the day on Sunday across Central Virginia. An arctic front is sweeping across the region on Saturday which will set the stage for cold air damning to set up on the day Sunday. The arctic front will stall across the Carolinas on Sunday while two separate pulses of energy will overspread precipitation on Sunday morning. Initial NWS forecast calls for sleet and freezing rain in the morning, followed by freezing rain changing to rain in the afternoon. Temperatures will likely be marginal at best for ice accumulation in Metro Richmond, but will be worth watching to see how much actually accumulates during the day Sunday.
A chance for some sleet is possible on Tuesday morning followed by some back end snow on Wednesday afternoon. Upwards of 2-3″ of rain is forecast for the Richmond area on Tuesday and Wednesday. If snow occurs on Wednesday, accumulations are expected to be light.
NWS Forecast from 11/25/2013

* Comments: A rain/snow mix started shortly after 1:15 PM. The snow persisted for about 20 minutes. Precipitation ended around 2 PM. No accumulation of snow was observed due to high air and ground temperatures. This was the first snow event of the 2013-2014 winter season.
Hurricane Sandy blew to the east and north of Richmond before becoming a hybrid storm slamming into the New Jersey Coast on October.
My observations of the storm were pretty tame. In Church Hill, we encountered mostly light to moderate rain with sustained winds around 5-15 MPH. Wind gusts approaching 25-35 MPH were infrequent. Recorded rainfall at my house was 2.25″.
NWS Path & Estimated TS Winds
Below is a collection of photos I saved from the event.
An arctic front will cross the region tomorrow bringing much cooler temperatures into Central Virginia. One feature of the system could be the season’s first appearance of snow. No accumulation is expected per the NWS forecast.
