Updated for Climate section
SYNOPSIS

High pressure will remain anchored offshore through the week, resulting in a prolonged period of heat.

NEAR TERM /THROUGH TONIGHT/

Isold/sct mountain showers and thuderstorms are still expected this afternoon before center of upper high drifts north and settles overhead tonight. High temperatures will be a deg or two warmer than yesterday and dewpoints a slightly higher pushing heat indices to near 100F over western MD and the eastern WV panhadle warranting a Heat Advisory.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/

Center of upper high will be overhead Wed and Thu promoting large scale subsidence/sinking motion and inhibiting t-storm development everywhere. Guidance indicates slightly lower temps and dewpoints Wed likely as a result of low-level flow coming off of the Atlantic Ocean and not from a continental trajectory.

LONG TERM /FRIDAY THROUGH MONDAY/

Upper level ridging along the East Coast will flatten out as we head into the weekend. As this occurs, the 850 hPa high will shift to our south, which will cause 850 hPa flow to turn southwesterly. This will result in a more continental source region for the airmass and even hotter temperatures. High temperatures in the mid-upper 90s appear likely Friday through Sunday, with 100 degrees not entirely out of the question. Dewpoints will also increase into the upper 60s to lower 70s during that time, causing it to feel more humid than preceding days. Heat indices in excess of 100 appear likely during that time for much of the forecast area. There will be lesser relief at night as well, as overnight lows increase into the middle to upper 70s by the weekend to the east of the Blue Ridge (upper 60s to lower 70s further west).

The combination of rising surface temperatures and dewpoints, along with decreasing temperatures aloft as the upper ridge breaks down will lead to an increase in instability, decrease in capping, and a return to thunderstorm chances each afternoon and evening.
Thunderstorm activity is expected to remain relatively isolated on Friday, and primarily confined to locations west of the Blue Ridge.
Thunderstorms coverage should increase slightly on Saturday as mid- level heights continue to slowly fall. Most model guidance shows a well defined upper trough tracking through the Great Lakes sometime during the Sunday-Monday timeframe, but there's variance in timing between the individual models. As large scale ascent associated with that trough increases, so will the coverage of afternoon and evening thunderstorms.

AVIATION /08Z TUESDAY THROUGH SATURDAY/

VFR conditions through 12Z Fri. SE winds around 10kt during the day becoming S around 5kt at night.

Prevailing VFR conditions and southerly winds are expected at the terminals on Friday and Saturday. A stray afternoon or evening thunderstorm can't be ruled out either day.

MARINE

South to southeast winds will prevail through much of the week. Southerly channeling combined with bay/river breeze enhancements likely result in SCA level gusts this afternoon and evening.

Winds may near low-end SCA levels in channeled southerly flow during the afternoon/evening hours on both Friday and Saturday.

TIDES/COASTAL FLOODING

Persistent southerly flow continues, and tidal anomalies are hovering near one to one and a half feet above normal. This is causing minor flooding at Annapolis early this morning.

CLIMATE

Hot temperatures are expected much of this week and especially this coming weekend. The hottest days appear to be Friday through Sunday when several records could be in jeopardy. Below is a list of record high temperatures for today Jun 18th, 21st, 22nd, and the 23rd and the year the record was set, and the current forecast high temperatures for those days.
