Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 401 AM EDT Thu Jul 2 2020

SYNOPSIS.

Upper level trough offshore will continue to pull away from the area today and tonight. A weak backdoor cold front will enter the area Saturday night before dissipating early next week.

NEAR TERM /THROUGH FRIDAY NIGHT/.

Departing upper level trough and building upper ridge from the Great Lks will result in upper level convergence/height rises over the area today through Friday. This will lead to a warming and drying trend with little or no chance of any convection except for a slight chance of a t-storm in Harford County Fri afternoon as backdoor front pushes southwest through southern NJ and southeastern PA.

Temperatures today should hit 90 with mid-upper 90s on Fri as 850 mb temps soar to near 22C. Dewpoints will be on the decrease as dry air aloft mixes down on light northerly winds. Still hot nonetheless with heat indices in the mid 90s.

SHORT TERM /INDEPENDENCE DAY/FOURTH OF JULY/.

Global models indicate some cooling will occur in the sfc to 500 mb layer that may weaken the subsidence inversion enough to allow isolated t-storms to develop. Models show isold convection developing in between the I-81 and I-95 corridors and the northern Chesapeake Bay north of Annapolis. While temps won't be as hot as on Fri, humidity will be on the rise with heat indices similar to Fri. Still no heat advisories are anticipated at this time.

LONG TERM /SUNDAY THROUGH WEDNESDAY/.

A remnant backdoor frontal boundary is expected to stall out on Sunday while oriented from portions of Central Virginia northwestward toward the West Virginia Panhandle. While thunderstorms can't be ruled out anywhere across the forecast area, the highest coverage of storms will likely lie near the boundary across western portions of the forecast area. Temperatures are expected to be slightly lower than preceding days, with highs generally in the upper 80s to near 90. Conditions will once again be humid, with dewpoints in the upper 60s to near 70.

The large scale flow pattern will remain largely unchanged throughout the upcoming week. At the start of the week, troughing will reside over the western US, with ridging over the center of the country, and weak flow aloft locally. Over the course of the week, higher heights aloft will gradually spread eastward as the flow pattern across the CONUS gradually starts to flatten out.

A hot and humid airmass will be in place at the start of the week, and remain in place through the duration of the long term period. Heat will be the main issue next week, with highs expected to soar well into the 90s each day. When combined with dewpoints in the 60s to near 70, heat indices will be in the 90s to near 100 each afternoon. Little relief will be felt at night, with lows in the 70s for most. Chances for diurnal thunderstorm activity will exist within the hot and humid airmass. With weak flow aloft, and no well defined mid-upper level disturbances passing through, terrain and bay breeze circulations could serve as the primary sources of lift leading to the development of afternoon thunderstorms.

AVIATION /07Z THURSDAY THROUGH MONDAY/.

Isolated t-storms Independence Day. A backdoor front Sat night will bring a wind shift to NE winds and perhaps some lower cigs.

Prevailing VFR conditions are expected at the terminals on Sunday and Monday, but temporary drops to sub-VFR conditions may be possible in association with any thunderstorms that form.

MARINE.

Isolated t-storms northern Ches Bay Fri and Sat.

Sub-SCA level winds are expected over the waters on both Sunday and Monday. Higher winds may be possible in association with any thunderstorms that form.

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.
