AREA FORECAST DISCUSSION National Weather Service Wakefield VA 118 PM EDT Sun May 31 2020

SYNOPSIS. High pressure builds into the region through mid week. A warm front lifts north of the area Tuesday night.

NEAR TERM /UNTIL MIDNIGHT TONIGHT/. As of 120 PM EDT Sunday .

A broken cloud deck in the SE portion of the CWA continues to erode and move SE this afternoon. Few to scattered cumulus continue to increase in coverage from the NW this afternoon/evening ahead of the next shortwave which begins to push through the region late this evening. Expect clouds to move out of the area overnight. Temperatures are currently in the low 70s and are expected to warm into the mid 70s for highs over the next few hours.

SHORT TERM /MIDNIGHT TONIGHT THROUGH WEDNESDAY/. As of 330 AM EDT Sunday .

Mostly clear/comfy tonight. Lows upper 40s-mid 50s (mid 40s at LKU). Mostly sunny Mon as the high pushes se across the region. Highs in the low-mid 70s. The high slides off the NC coast Mon night. Mostly clear to start with some overnight clouds as a trof approaches from the north. Lows in the 50s.

Low pressure moves east across the nern states Tue while the high becomes centered off the Carolina coast. Models differ wrt the movement of a convective complex across Pa. NAM drops in se across the area Tue afternoon while the GFS is slower and closer to the coast along a developing warm front that extends east to near the Delmarva. Meanwhile, both the ECMWF/Canadian not impressed with any complex. So for now, added slight chc PoPs across the Delmarva Tue afternoon and evening. This will likely change with later model runs as is typical with any convective complex in a nw flow. Warmer with highs upr 70s- lwr 80s west of the Ches Bay but remaining in the low-mid 70s over the ern shore. Lows Tue night in the mid-upper 60s.

The Bermuda ridge dominates Wed with the first widespread 90 (+) degree day the year (H85 temps btwn 18C-20C). Mostly sunny as any convection stays to the north. Highs in the upper 80s-lower 90s except low-mid 80s at the beaches.

LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/. As of 330 AM EDT Sunday .

Another convective complex is progged to slide se in the nw flow Thurs. It will be another hot day before any convection dvlps. Highs near 90 over most of the piedmont with mid to upper 80s along the coast and low to mid 80s along the Eastern Shore.

The ridge remains in place through the extended period (centered to our west) and temps will remain in the mid to upper 80s Friday and Saturday, except along the Eastern Shore where temps will be slightly cooler in the low 80s. Lows throughout the extended are expected to be generally in the upper 60s to around 70F.

Due to the positioning of the ridge, we will be located on the ern side of it and therefore NW flow will dominate with a series of s/w's moving around the ridge producing periodic convection.

AVIATION /17Z SUNDAY THROUGH THURSDAY/. As of 620 AM EDT Sunday .

VFR conditions thru the forecast prd as high pres builds in from the nw. BKN AC deck this morning with SCT CU this aftrn. North winds 10-15 kts with gusts to 20 kts along the coast.

OUTLOOK . VFR conditions through Tues as high pres spreads across the region. The high moves offshore Wed/Thur with a chc of diurnal convection.

MARINE. As of 100 PM EDT Sunday .

Cold front is now well south of the waters early this aftn. N-NNE winds are still gusting to around 20 kt over the Ches Bay/Lower James River, with 20-25 kt gusts across the srn coastal waters. Waves on the Ches Bay are 2-4 ft with seas of 3-3.5 ft N/4-5 ft S. Winds, waves, and seas are still expected to drop to below SCA criteria later this afternoon but another CAA surge arrives tonight-Mon AM as winds turn more to the NNE. The consensus of the latest 12z/31 guidance shows a brief (3-6 hour) period of 15-20 kt sustained winds on the Ches Bay/ocean, while local wind probs of sustained 18 kt winds have risen to nearly 50% across much of the Ches Bay. This is in addition to the fact that 925 mb temperatures are progged to drop to 6-8C late tonight with the CAA surge (coupled w/ water temperatures in the mid-upper 60s on the bay), which will promote mixing of slightly higher winds closer the top of the boundary layer. Given the above factors, have opted to extend the SCA through 7 am for the upper Ches Bay/10 am for the Lower Ches Bay/Lower James River (given that the break between SCA conditions will be brief . and sustained winds will only diminish to 10-15 kt). Timing of highest winds Monday morning looks to be from 04-10z N/06-12z S. Still anticipate that wind speeds/gusts will be just below SCA criteria on the ocean, with seas staying below 5 feet in most areas (seas could briefly touch 5 ft over the NE NC coastal waters Mon AM). Will look at possibly extending the SCA for the Currituck Sound through Mon AM with the afternoon update.

Winds become light during the day on Mon as high pressure becomes centered over the waters. Conditions will remain sub-SCA into Tuesday with winds becoming SW again by Monday night. Could see a brief uptick in SW winds (to near SCA criteria over the Lower Bay/srn coastal waters) late Tue-Tue night in advance of a weak trough of low pressure at the sfc. Winds become more westerly (w/ speeds of 10-15 kt) during the day on Wed.

AKQ WATCHES/WARNINGS/ADVISORIES. MD . None. NC . None. VA . None. MARINE . Small Craft Advisory until 10 AM EDT Monday for ANZ632-634-638. Small Craft Advisory until 4 PM EDT this afternoon for ANZ633- 656-658. Small Craft Advisory until 7 AM EDT Monday for ANZ630-631.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
