AREA FORECAST DISCUSSION National Weather Service Wakefield VA 810 PM EDT Thu Aug 13 2020

SYNOPSIS. A trough of low pressure across the area, will result in numerous showers and and thunderstorms through Friday. A cold front pushes south into Virginia Friday night, then stalls near the Virginia North Carolina border over the weekend.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. As of 725 PM EDT Thursday .

Although ISOLD/SCT SHRAs/tstms remain . coverage/rainfall rates continue to diminish Therefore. will be canceling the Flash Flood Watch shortly. Remaining mostly cloudy overnight w/ patchy FG. Lows mainly 70-75F.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/. As of 300 PM EDT Thursday .

Unsettled weather continues into Sunday. Latest NWP guidance suggests that Friday will see continued showers and storms, perhaps focused more east of I-95 as moisture wraps into the area on the west side of the surface low just off the coast. Still, will go with likely pops everywhere on Friday afternoon given the high precipitable water values > 2.0" on Friday. Another area of low pressure develops over the Great Lakes through TN Valley on Friday associated with a weak upper trough. This combined with the continued trough just south of the area will allow for another round of showers and storms during the day on Saturday into Saturday night. Again, with precipitable water values at or above 2 inches, could not rule out heavy rain again. The GFS and ECMWF continue to show the surface trough nearby even into Sunday so another day of showers/storms with locally heavy rain possible again especially Sunday afternoon.

Overall, highs in the mid 80s each day with lows in the lower 70s. Continued very muggy through the weekend.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 1250 PM EDT Thursday .

An upper trough axis digs into the Great Lakes and northeast early next week, then eventually elongates southward to the GOMEX by the middle of next week. Unfortunately, this means the unsettled pattern will stay with us through much of next week. Monday/Tuesday look to be the least active days (lowest PoPs for next week) with PoPs in the 25-40% range. They then ramp up again by the middle and end of next week. Am not expecting as much heavy rainfall potential as the precipitable water values will not be as high as they are now. Otherwise, temperatures should be seasonable with highs in the mid- upper 80s and lows in the mid 60s to lower 70s.

AVIATION /00Z FRIDAY THROUGH TUESDAY/. As of 810 PM EDT Thursday .

Showers and storms are beginning to taper off this evening. Primarily VFR/MVFR conditions will prevail through late tonight before ceilings lower to widespread MVFR and isolated IFR heights. The greatest chance for IFR ceilings will be between 09-13z. Patchy fog will once again be possible between 06-13z. Shower/storms chances increase once again tomorrow afternoon into the evening but will keep the mention of thunder out of the TAF for now. Winds are generally NE 5-10 kt but will become light and variable tonight. Primarily VFR/MVFR tomorrow although any heavy shower/storm has the potential to briefly drop visibility to IFR.

Outlook: Nmrs shwrs/tstms continue through Sunday as deep moisture continues to along the the sfc trof/cold front.

MARINE. As of 400 PM EDT Thursday .

Surface area of low pressure is located across eastern North Carolina this afternoon. Winds have become easterly 10-15 kt, with a few brief gusts up to 20 kt. These conditions will continue into Friday. The center of the low is expected to track off the coast, between VA Beach and Kill Devils Hill NC, Friday evening. As the low moves off the coast this weekend, winds will likely become NE 10-20 kt (highest winds still expected for the northern coastal waters). High pressure will be building in from the north as well, enhancing the pressure gradient between it and the low pressure off the coast.

Waves in the Chesapeake Bay will be 1-2 ft through the forecast period. Seas will build from 1-2 ft today and Friday to 3-5 ft this weekend and into early next week.

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