AREA FORECAST DISCUSSION National Weather Service Wakefield VA 113 AM EDT Thu Aug 5 2021

SYNOPSIS. A stationary front will linger off the coast tonight and Thursday as high pressure builds across the Mid-Atlantic. High pressure slides offshore Friday.

NEAR TERM /UNTIL 6 AM THIS MORNING/. As of 1025 PM EDT Wednesday .

Weak sfc lo pres INVOF coastal NE NC tracking slowly NE along frontal boundary just offshore right now and will continue to the NE overnight. Clearing taking place inland while lingering BKN CIGS (and spotty light pcpn) remain near the coast. The boundary will be nudged a bit more offshore by late tonight. Expecting clouds to remain stubborn at the coast. Lows from the u50s-l60s inland to the m60s towards the coast.

SHORT TERM /6 AM THIS MORNING THROUGH SATURDAY NIGHT/. As of 400 PM EDT Wednesday .

The upper trough to the west will continue to lift NE and shear out during the day on Thursday. With the weak surface high overhead and the front off the coast, should see mainly dry weather across the region on Thursday with highs warmer than today thank to some returning sunshine. Expect highs in the low to mid 80s. The dry weather should continue Thursday night into Friday as the sfc high slides off the coast and the height also rise. This will allow for some additional heating on Friday with highs getting back into the mid to upper 80s.

For Friday night into Saturday, there is expected to be another upper level shortwave trough that will push eastward and bump into the western Atlantic Upper level ridge. The timing on when the trough will arrive and how much moisture it will have with it is still uncertain. The 12z model runs are a little slower and focus things more for Saturday. So with the uncertainty on timing and areas that could see rain and storms, have reduced the NBM pops to chance values across the southern portion of the area on Friday night and chance to low likely on Saturday. The Southeastern portion of the area seems like the best bet for rain. With the clouds and rain expected have gone lower on temps back into the low to mid 80s, but this is also timing dependent as a slower onset of rain could allow more warming.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. As of 200 PM EDT Wednesday .

Summer will return in the extended period as the upper level ridge over the SERN US builds and extends from the Western Atlantic into the Lower MS Valley. As the height rise, so will the temperature and humidity. Expect High temperatures to build into the upper 80s to lower 90s on Sunday and then in the low to mid 90s for the early part of next week. While an isolated shower is possible due to the day time heating on Sunday through Tuesday, most areas will be dry as their is little in the way of lift for any organized convection. By Wednesday however, the GFS and ECMWF both show a shortwave trough moving across the Great Lakes and Ohio Valley which could knock down heights and become a focus for convection. Otherwise, expect typical August weather over this time period.

AVIATION /05Z THURSDAY THROUGH MONDAY/. As of 735 PM EDT Wednesday .

Mainly MVFR-VFR conditions over the FA attm. Weak sfc lo pres INVOF coastal NE NC tracking slowly NE along frontal boundary just offshore right now and will continue to the NE this evening/overnight. Frontal boundary expected to very slowly nudge E into Thu. BKN MVFR CIGS and VCSH will stay in forecast for PHF/ORF/ECG until around/after midnight. Improvement expected thereafter. The next CHC for MVFR conditions would come on Sat as more showers and thunderstorms are possible as moisture from the Gulf Coast states moves northward to over the mid-Atlantic states.

MARINE. As of 100 AM EDT Thursday .

Have allowed the SCA headlines in the main portion of the Ches bay to expire as of 1 am with N/NE winds averaging around 15 kt, but given seas to 6ft at buoy 44099 not too far from the mouth of the Bay decided to extend the SCA for the mouth of the Bay through 7am for lingering 4 ft waves.

Previous discussion . A stalled frontal boundary remains located along the coast this evening. A closed area of sfc low pressure has formed near Cape Hatteras today. This sfc low will be tracking north along the coast tonight. Winds will remain NNE 15-20 kt for most of the local waters except for the rivers and Currituck Sound over the next few hours before gradually becoming N after midnight as the low tracks across the area. Will allow the SCAs for the Lower James and Currituck Sound to expire at 10 PM. SCAs will continue for the Ches Bay until 1 AM and will continue into early Thurs morning for the coastal waters. Winds will become N 10-15 kt late Thurs morning and continue to fall through the afternoon. Seas are 6-7 ft south of Cape Henry and 5-6 ft north. Seas are anticipated to drop through the day on Thurs. High pressure become the dominate feature for the weekend and into early next week. Sub- SCA conditions are expected after Thurs morning.

CLIMATE. As of 1020 PM EDT Wednesday .

The high at SBY today has been 73 which would tie the record low maximum temperature for the date OTW. RIC/ORF/ECG had highs above their records (for low maximum temperature).

For reference they have been included below:

* RIC: 73 (1966) * ORF: 68 (1912) * SBY: 73 (1948) * ECG: 74 (1950)
