Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 241 PM EDT Sun Jul 5 2020

SYNOPSIS. Surface high pressure continues to build over the Atlantic through Tuesday. Meanwhile, upper-level ridging builds in across the area as well. Cutoff low pressure will develop to the south for Wednesday and it may impact the area late in the week.

NEAR TERM /THROUGH TONIGHT/. Current temperatures are not quite as warm as had been expected for much of the area, but still in the upper 80s to low 90s. Expect to add a degree or two to that for the highs today. Dew points are in the low to mid 70s for most of the area, keeping heat indices generally in the mid-upper 90s and even near 100 in a few spots. As a result of this very warm and humid airmass, starting to see several thunderstorms pop up across the area. The environment is characterized by 2500-3500 J/kg of MLCAPE, upwards of 1300 J/kg of DCAPE, but very little in terms of shear overall, with only 20-25 knots over northeast MD, decreasing further south and west. Coverage of storms has been best over central VA thus far, coming off of the higher terrain. However, we are beginning to see storms fire off of the river/bay breezes in central and northeast MD. Storms are expected to continue into this evening. SPC has put much of the area under a marginal risk for severe weather this afternoon. Given the DCAPE present across the region, any storm that really gets going is bringing down some wind. The lack of shear should allow for a more pulse-type storm environment, rather than longer lived multicells. However, in a similar environment yesterday, there was one storm that proved that theory wrong, so can't rule out an isolated more organized cell somewhere. Storms have generally been slow-moving thus far, but flooding isn't expected to be much of an issue given the lack of any well defined surface boundaries, and the presence of mid-level dry air, which should facilitate strong cold pool production and resultant propagation of storms.

Storms should quickly die off this evening as we lose daytime heating. Areas of patchy fog may be possible, especially to the west of the Blue Ridge, where winds are more likely to go calm within sheltered valleys. Lows tonight will range from the mid 60s in the mountains to the mid-upper 70s in the urban areas.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. With surface high pressure remaining in place over the Atlantic, and upper-level ridging building in overhead, expect much of the same on Monday and Tuesday. High temperatures will reach into the low-mid 90s, with continued high humidity leading to heat indices in the mid-upper 90s each afternoon. In fact, lows Monday and Tuesday night only get down into the low 70s for most areas (upper 60s in higher terrain and mid 70s in DC/Baltimore).

On Monday, things get a little more interesting. A weak upper- level shortwave will pass overhead in this very unstable environment. While weak, this shortwave will provide a little bit more shear than we have had in recent days. Given the combination of 20-25 knots of deep layer shear and high instability (2000 J/kg or so), should see some more intense and organized multicell clusters. For that reason SPC has place much of the forecast area under a marginal risk for severe weather on Monday. Damaging winds would be the primary risk with any storms, but some hail cannot be ruled out as well.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. A warm and potentially fairly stormy pattern exists through the long term. To start, on Wednesday a weak upper low be near or just south of the region. This low lingers Thursday. The location of this low will help dictate how stormy the weather is, with a closer locale likely resulting in more afternoon thunderstorms and slightly cooler temperatures. Friday and Saturday, uncertainty grows, with some guidance kicking the upper low east ahead of a stronger trough approaching from the west, while others keep the low around. This will significantly affect the forecast, but uncertainty is high. Bottom line, however, is that slightly warmer than normal temperatures are likely, but the extent of thunderstorms is a more uncertain.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. Generally expecting VFR at all terminals through Tuesday. However, there will be a chance for afternoon showers and storms each day, given the hot and humid air mass we are stuck in. This threat will generally end once the sun sets each evening.

Most of the activity thus far this afternoon has been near CHO, but will continue to keep TSRA in DCA/BWI between 20-22z, with greatest confidence in a storm hitting one of the terminals. VCTS remains for IAD and MTN as well, but think they may just get by without a direct hit this afternoon. Will continue to monitor radar and update as needed.

Main concern Wednesday and Thursday will be potential for early morning fog and afternoon thunderstorms. Both of these concerns are most likely to affect CHO and MRB.

MARINE. Light southerly winds (below SCA) are expected over the waters through Tuesday. Isolated to scattered showers and thunderstorms are expected each afternoon today through Tuesday. Special Marine Warnings may be needed for any stronger storms that form.

Mainly light winds on the waters Wednesday and Thursday, with the primary hazard being potential for afternoon thunderstorms both days.

TIDES/COASTAL FLOODING. Southerly flow continues over the next several days, which will help to keep anomalies generally elevated. Could see minor coastal flooding in many of the same spots this evening/tonight yet again. For now though, am holding off, as subtle shifts in the wind speed/direction could lead to quick drops in the anomalies, which could quickly bump the forecast back down. So, will hold off on any advisories at this time.

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.

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