AREA FORECAST DISCUSSION National Weather Service Wakefield VA 346 PM EDT Sun Apr 18 2021

SYNOPSIS. Another weak disturbance crosses the region tonight into Monday, bringing additional chances for light rain late this afternoon through midday Monday. Weak high pressure builds over the region later Monday night through Tuesday evening, bringing drying conditions. A cold front crosses the region on Wednesday bringing another chance for showers.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. As of 320 PM EDT Sunday .

Latest analysis reveals a sfc trough inland across the piedmont this aftn, with weak sfc high pressure in place just offshore. Upper air analysis showing next weak shortwave crossing the mid-south this aftn, with low amplitude ridging downstream across the deep south into the lower Mid-Atlantic. The mid-aftn satellite showing SCT-BKN CU field over the northern half of the area with some mid- level cloudiness providing opaque/veiled sunshine over the southern half of the area. Not much in the way of precipitation over the area just yet, though regional radar mosaic showing some isolated showers over the Blue Ridge and foothills just to our NW.

Rain chances ramp up across the area tonight into Monday morning. Not much more tonight than we saw last night, with some iso-widely sct light showers/sprinkles this evening, focused mainly along a FVX-SBY axis . but even at that a few hundredth at most can be expected. Early morning lows fall back into the 40s to near 50 once again.

SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/. As of 345 PM EDT Sunday .

Rain chances ramp up around and just after sunrise on Monday, likely to linger into the afternoon/early evening along the coast, as the upper ridging takes a bit longer to clear out the upper shortwave. QPF tonight through Monday, with generally up to 0.10" west of I-95, 0.10"-0.25" across the SE. Modest instability and some weak lift is evident in model forecast soundings along the coastal plain. Thus, while no strong to severe storms are anticipated at this time, have included a slight chance for thunder from midday through the evening. Drier weather is expected by Monday night, with clearing from NW to SE Mon night through Tuesday morning, as weak high pressure returns to the region, ahead of the next frontal system for midweek. Tuesday looks to be dry across the local area. A weak low slides along the Carolina coastal plain later Tue morning into the afternoon, but will be too far to our south for much more than some late day clouds for Hampton Roads.

Highs Monday similar to the past couple of days with readings in the mid 60s to low 70s.Breezy and milder in return flow ahead of the approaching front, with highs in the low to mid 70s inland, upper 60s to low 70s eastern shore. Early morning lows in the 40s inland to near 50 degrees along the coast Tue morning, and in the 50s Wed morning.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. As of 345 PM EDT Sunday .

Potent mid-upper trough and attendant sfc cold front crosses the region later Wednesday into Thursday morning. With the sfc low crossing the eastern Great Lakes, associated best lift/dynamics look to remain confined to our north. Nevertheless, still appears we'll see enough to warrant t-storm mention for most of the area late Wed aftn and evening, in anticipation of some gusty showers/embedded T-Storms.

While Sct to numerous showers are expected, greatest impact with this system still appears as if it will be with pressure falls and resultant gusty winds along and behind the frontal passage Wed night and Thursday. After a breezy, mild start to the day Wednesday, with highs in the 60s to low 70s, expect a breezy, chilly night Wed night. BL should remain well-mixed for most of Wed night, but there is potential for frost or brief light freeze mainly well inland Thursday morning with temperatures dropping into the low to mid 30s (mid 30s to low 40s farther east.

Thursday will be dry, but cool and breezy, with the upper low pivoting through and cool high pressure building across the mid- south. Highs Thu in the lower 60s. A widespread freeze appears quite/(more?) possible on Thursday night, with ideal radiating conditions as sfc high builds overhead. Another slate of Frost/Freeze headlines may well be needed. Will refrain from HWO mention at this time due to late week timing, but we'll continue to monitor.

Remaining dry Friday with sfc high pushing offshore. Resultant return flow allows temperatures to moderate slightly some, but remaining below average, with highs in the mid to upper 60s with early morning lows in the upper 30s to mid 40s. Another sfc low and associated cold front potentially impacts the region by next weekend. That system is of Pacific origin, so not quite as strong of a CAA surge behind that system, but rain chances appear to ramp back up with its arrival. Kept PoPs no higher than low end chance with GFS/ECMWF still not in line with synoptic details.

AVIATION /19Z SUNDAY THROUGH FRIDAY/. As of 1215 PM EDT Sunday .

VFR conditions are expected to continue through the 18z forecast period. Increasing CU field this aftn, though remaining VFR (bases 6-8 kft AGL). Sfc winds will generally remain than 10 knots this aftn. CIGs lower slightly this evening, as another weak system approaches the region. Some isolated/widely scattered light rain showers will be possible late tonight into early Monday morning.

OUTLOOK . Light rain chances will linger through Monday morning (potentially Monday afternoon east) Mainly dry from Mon aftn through Wed morning with high pressure returning. Some flight restrictions will be possible as a front moves into the region later Wed and Wed night.

MARINE. As of 345 AM EDT Sunday .

Fairly benign marine conditions again today. Weak low pressure is well off the Carolina coast and our local area remains under the influence of high pressure to the west. Winds are light 5-10 kts with generally onshore flow. Waves around a foot, and seas 2-3 ft. A weak boundary will approach the area overnight into Monday morning before washing out over the area. Expect S/SE winds to increase slightly to 10-15 kts late tonight for a brief period before decreasing back to 5-10 kts early Monday morning. Another weak area of low pressure will ride up the Carolina coast on Monday before pushing out to sea late Monday, with high pressure building back in for Tuesday. Winds by Monday afternoon are expected to become northerly 10-15 kts and then W/SW 5-10 kts late Monday into early Tuesday. With high pressure moving off the coast on Tuesday, winds will become S/SE 10-15 kts beginning Tuesday afternoon. Waves in the bay will be 1-2 ft on Monday and Tuesday, and seas will remain 2-3 ft. A strong cold front crosses the area late Wednesday with SCA winds/seas expected beginning late Wednesday afternoon and lasting through Thursday.
