AREA FORECAST DISCUSSION National Weather Service Wakefield VA 847 AM EST Mon Dec 9 2019
SYNOPSIS. Low pressure moves off the Delmarva Peninsula today. Strong low pressure tracks across the Great Lakes later today and into eastern Canada Tuesday. The trailing strong cold front crosses the area Tuesday night. High pressure returns late Wednesday and Thursday.
NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 845 AM EST Monday .
Fog has persisted across the area this morning, so have issued another SPS until 1030 AM to account for it. Visibilities will average between 1/4-1/2 mile. Expect the fog to slowly dissipate later this morning as winds increase/low-level mixing improves.
Previous Discussion as of 630 AM EST:
Latest MSAS has the sfc low and assctd pcpn ivof the Ches Bay and is progged to lift ne off the Delmarva peninsula today. Radar trends have shown the steady rain with systm having shifted offshore (even some thunder noted in some convective cells offshore). Abundant low level moisture along with an apprchg s/w energy has resulted in areas of rain/drizzle and fog to quickly develop west of the Ches Bay where it rained last nite. Have issued a SPS to cover this thru the morning commute.
Models continue to show the energy from the mid level impulse tracking nne of the area today with its pcpn shield tracking across the nrn half of the local area as the day progresses. This also results in an insitu-wedge developing across the nwrn zones given the fact that it did not rain there last nite. Pcpn becomes more spotty in nature across the e-se with any shwr chc tapering off this aftrn. Temps tricky, but milder than recent days. Expect highs to range fromthe low-mid 50s nw to the upr 60s se where BINOVC allows for some partial late day sun.
SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/. As of 335 AM EST Monday .
Little if any temp drop tonight due to the SW flow and WAA in place ahead of the cold front apprchg the mts. Little support for pcpn, but enuf lingering moisture exists for a few shwrs across the north. Looks like a cloudy and mild nite with more low stratus than fog. Lows in the 50s to near 60 se.
Tues to the the "in btwn" day with not much occuring until the moisture ahead of the apprchg cold front enters the fa during the aftrn. It starts off cloudy and mild with little support for any pcpn thru 18Z. Clouds break up a bit across the se while shwrs spread east of the mts by late aftrn. Unseasonably warm along with a breezy sw wind. Tuff call on whether the nwrn most zones erode the wedge completely so for now will hold temps in the low-mid 60s there. Otw, temps rise to arnd 70 east of I95 with mid 70s across the se. See CLI section below for record high temps.
The cold front crosses the area Tues night with likely/categorical PoPs through 12z. Models now showing the potential for a pcpn type issue arnd 12Z Wed across the nrn most zones. While the thicknesses crash as the colder air rapidly follows the fropa, sfc and wet bulb temps remain above freezing. Much like the mid Nov event, pcpn intensity will likely determine whether and how much wet snow can mix in with the rain. Thus, adjusted the grids a bit to reflect a svrl hr prd (09Z-15Z) Wed for a rain/wet snow mix. For now, think this occurs btwn 09Z-12Z across Louisa/Fluvanna then btwn 12Z-15Z from Louisa ne to nrn Carolina to Dorchester. No accumls expected attm. Lows Tue nite mid 30s nrn zones to low-mid 40s srn zones.
Likely PoPs Wed morning with decreasing PoPs west to east Wed aftrn as the cold front moves offshore. In fact, wrn zones will likely become ot sunny late. Not much rise in temps given the clouds and CAA. Highs in 40s.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 355 PM EST Sunday .
Strong high pressure over the upper Midwest will build into the region Wednesday night. Strong cold advection on northwesterly winds will lead to overnight low temperatures in the low to mid 20s NW, mid to upper 20s for the I-95 corridor, and upper 20s and low 30s for SE VA and NE NC. The aforementioned surface high will become centered over/just north of the local area on Thursday with decreasing clouds and winds. Daytime high temperatures will only make it into the upper 30s and low 40s on Thursday. Models have come into much better agreement and all now keep the area dry on Thursday and Thursday night. Chilly overnight lows range from the low 20s NW to upper 30s SE.
Surface high pressure continues its eastward migration on Friday but will still extend ridging to the SW along and east of the higher terrain. GFS/ECMWF solutions diverge regarding timing for the expected wet period late week into the weekend with the GFS around 12 hours faster than the ECMWF. Will increase PoPs slowly from the south/southwest during the day on Friday but the bulk of the precip is expected to fall Friday night into Saturday as low pressure lifts northward across the region. Given the slower timing, high pressure will have moved well away from the favored area to supply cold/dry air to the region and concerns for mixed precipitation have decreased. High temps on Friday range from the low 40s NW, close to 50 degrees for the Richmond metro, and low to mid 50s for areas east of I-95. Not looking particularly cold behind the weekend system either, highs in the 50s Saturday and Sunday with lows in the upper 30s and low 40s.
AVIATION /14Z MONDAY THROUGH FRIDAY/. As of 640 AM EST Monday .
Low pressure ivof the Ches Bay this morning tracks nne along then off the Delmarva today. IFR CIGS/VSBYS continue in light rain/drizzle and fog to start off the forecast period as abundant moisture remains ahead af an upr lvl systm apprchs from the west. Expect improving conditions at PHF/ORF/ECG by late morning or erly aftrn but the clow clouds and sporatic pcpn continues at both RIC/SBY for most of the daylight hrs. LGT/VRBL winds become SW this aftrn. The pcpn tapers off and ends across the area tonite.
OUTLOOK . The area will be largely rain free late tonite into Tue morning. with localized reductions in CIGS/VSBYS tonite due to areas of fog/stratus. Periods of lower CIGS/VSBYS in both rain/shwrs are likely Tues aftn through Wed morning, as low pressure tracks well to our NW. A trailing cold front will cross the area Tues night. High pressure builds into the area for Wednesday/Thursday.
MARINE. As of 335 AM EST Monday .
Latest analysis shows a warm front that extends northward and parallels the coastal waters. Winds across the coastal waters have already turned S/SE 15-20 kts, while winds across the bay on the other side of the front are still northerly 10-15 kts. Seas are 3-6 ft in the southern coastal waters and 3-4 ft in the northern coastal waters. Waves in the bay are 1-2 ft. The front will continue to advance north and a bit further inland today. Winds over the bay should become southerly this morning as a result. The increasing S/SW flow should bring winds in the bay and southern James up to 15- 20 kts by late Monday night. Winds over the coastal waters will remain S/SW 15-20 kts with gusts around 25 kts. Waves in the bay will build to 2-3 ft by Monday night with around 4 ft at the mouth of the bay. Seas will continue to build and by late Monday night will be 5-8 ft. SCA is now in effect for the coastal waters, and SCA will be issued for the Bay, lower James, and Currituck sound for later tonight through about 18Z Tuesday. Confidence is lower for SCA on the rivers outside of the lower James, so will leave them out for now.
With very warm conditions Tuesday during the day ahead of an approaching cold front, winds over the cold waters will likely diminish a bit (though seas on the coast will remain at or above 5 ft). SCA conditions likely for all zones Tue night/Wed AM as colder air moves in from the North. Potential for stronger winds Wednesday night into Thursday as a secondary cold surge arrives with strong high pressure building in from the North while low pressure lingers over the SE CONUS. Seas will also remain elevated through this period.
