AREA FORECAST DISCUSSION National Weather Service Wakefield VA 956 PM EST Mon Jan 20 2020

SYNOPSIS. Cold high pressure builds across the region through midweek. Much colder air spills across the region tonight through Tuesday . with temperatures slowly moderating for the latter half of the week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. As of 1000 PM EST Monday .

Latest wx analysis reveals strong/cold 1044+mb sfc high pressure over the northern and central plains. Winds have diminished tonight as the pressure gradient has weakened over the area. Temperatures have quickly falling into the 20s (temperatures remain in the low 30s near the southeast VA coast and northern Outer Banks). Winds chills will be in the teens tonight, not as low as last night with winds diminishing.

Bay streamer has redeveloped over the Chesapeake tonight, cannot rule our a few flurries across Norfolk, VA Beach, Chesapeake tonight. Otherwise, the rest of the area will see clear skies.

Otherwise, clear and cold tonight. Latest model guidance has trended toward winds not totally decoupling once again tonight, which should keep minima from falling quite as far as they could otherwise. Lows mainly in the upper teens to low 20s inland . mid to upper 20s SE coast. Some mid teens possible in typically cooler spots.

SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/. As of 250 PM EST Monday .

Continued cold and dry Tuesday, with highs remaining below normal despite plenty of sunshine. Thickness tools still mesh well with NBM and MOS guidance has consolidated in the mid to upper 30s, which also fits persistence quite well. Clear and cold once again Tuesday night with early morning lows in the low to mid 20s . to around 30 SE.

Models still showing positively tilted shortwave dropping from the mid-south to the GA/SC coast Tuesday night, eventually forming a closed low Wed morning. Models remain in good agreement in skirting this wave quickly farther offshore, with cyclogenesis occurring well away from the local area. Thus, expect any sensible weather impacts to be well away from the region.

Behind this wave, modifying sfc high builds over the Mid-Atlantic and northeast CONUS on Wednesday. Thicknesses begin to climb, signaling the start of a moderating temp trend that will continue through the upcoming weekend.

Slightly warmer Wednesday with highs climbing to near normal Wed, and just above on Thursday. Highs Wed in the low to mid 40s, under a mainly sunny sky. Lows Wednesday night will inch up a few degrees as well with generally low/mid 20s expected across the region. Highs in the upper 40s to low 50s under a partly to mostly clear/sunny sky.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. As of 400 PM EST Monday .

The end of the work week will be dry and mild, with high pressure at the sfc and aloft over the region. At the same time, an upper-level trough will be digging south into the Midwest/Central US. The trough will become a closed low and cut off from the main upper-level flow and slowly migrate east. As the closed low pressure aloft moves towards the east coast, it will likely stay northwest of the southern Mid-Atlantic. However, a sfc low will likely develop east of the Appalachian Mountains and track from SW to NE across VA/MD. This will bring an area of rain through the region Saturday morning. As the sfc low moves north of the area, rain will exit the area for Saturday evening/night. However, the low pressure system aloft will still be nearby and may give areas across central and northeastern VA and central Delmarva a few rain showers Saturday afternoon/evening. A NW, downslope, low will begin late Saturday/Sunday and dry the area out.

Throughout the Long Term period, temperatures will be near average to slight above average. Friday's high temperatures will be in the 50s with lows in the 20s/30s Friday morning. As rain moves into the area, temperatures and dew points will increase, temperatures on Saturday morning will range from the upper 40s across northeast NC and southeast VA to mid 30s across central VA and MD Eastern Shore. Temperatures during the day on Saturday will be dependent on the exact track of the sfc low pressure. High may reach 60 across Hampton Roads and northeast NC, while a CAD wedge may develop in the central VA Piedmont, keeping temperatures in the 40s. Temperatures for Sunday and Monday will be close to average for late January, highs in the mid-upper 40s and lows in the 20s/30s.

AVIATION /03Z TUESDAY THROUGH SATURDAY/. As of 800 PM EST Monday .

VFR conditions are expected to continue over the next 24 hours across the area. Skies has mostly cleared south of the Chesapeake Bay across southeast VA and the northern Outer Banks. However, a bay streamer has redeveloped over Norfolk (east of KORF) and VA Beach with CIGs FEW-SCT 040-050. Otherwise, clear skies are expected through Tuesday evening. Northerly have decrease from this afternoon and will remain N 5-10 kt.

Outlook: VFR conditions persist through Wed as cold high pressure builds back across the region.

MARINE. As of 400 PM EST Monday .

Late this aftn, high pressure was building in from the NW. Strong CAA is resulting in a NNW wind of 15-25 kt for the Bay/ocean/Currituck Snd, and 10-15 kt elsewhere. Seas are 4-6 ft with 3-4 ft waves in the Bay. The center of the high will continue to build toward the area from the NW tonight into Wed morning, then builds right over the region late Wed through Thu. As a result, N winds will continue to be 15-25 kt over the Bay, Ocean, and Currituck Snd tonight into at least early Wed morning. Waves will be 2-4 ft and seas will be 4-7 ft. Thus, have adjusted SCA headlines in most of these areas through at least Tue aftn or into early Wed morning. Low pressure develops well off the Southeast Coast Tue night into Wed, with the wind becoming NNE with speeds 10-15 kt N to 15-20 kt srn Bay, and 20-25 kt for the ocean S of Cape Henry. This will likely maintain at least 5-6 ft seas S, and could remain 6-8 ft Tue/Wed off the nrn Outer Banks. Elsewhere, seas subside to 3-4 ft, with 2-3 ft waves in the Bay.

High pressure builds right over the region Wed night into Thu and slowly slides offshore Fri. Low pressure and an associated cold front passes through the area Fri night into Sat.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
