| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 404am EDT Tuesday September 8 2026 .WHAT HAS CHANGED... No changes to the forecast. .KEY MESSAGES... - 1) Dry through mid week. - 2) Shower and thunderstorm chances return Thursday. - 3) Cooler and less humid conditions are expected on Friday, before humidity builds back in next weekend. KEY MESSAGE 1...Dry through mid week. Conditions will remain tranquil as high pressure persists over the Mid-Atlantic through Wednesday before gradually moving offshore. Large scale subsidence and dry air lead to a precipitation-free forecast with temperatures rising to several degrees above normal as the high pulls offshore. This leads to high temperatures in the mid to upper 80s today, perhaps near 90 Wednesday (slightly cooler in the mountains). Low temperatures (and dew points) will generally be in the 50s and 60s during this time. Some river valley fog is likely each morning. KEY MESSAGE 2...Shower and thunderstorm chances return Thursday. The upper-level ridge will begin to flatten out Wednesday before breaking down and pushing south and east into Thursday. Several pieces of upper-level energy rotating around an upper low centered over the Hudson Bay will slowly push a cold front south towards our region by Thursday. At the surface, high pressure pushing offshore will bring increasingly warm and humid conditions to the area, with highs in the 80s to near 90 with dew points in the upper 60s to low 70s, with the highest values being Thursday. Model guidance over the past 24 hours has come into better agreement in regards to the progression of the front on Thursday, as well as the upper-level pattern in association with it. The front really looks like it will flatten out as it moves southward, and really loses the upper-level support. The timing of peak heating and the highest shear just doesn't look to line up at this point. There may be some jet-induced showers and storms late Thursday as we move into the right entrance of the upper jet centered over New England, but not necessarily expecting those to be severe at that point, as the front should be largely through the region. At this point, the severe weather threat looks very limited, but any storm that develops on the warm side of the boundary could bring some gusty winds along with it, but the lack of a substantial wind field will really make that more difficult with southward extent. KEY MESSAGE 3...Cooler and less humid conditions are expected on Friday, before humidity builds back in next weekend. High pressure will build to our north on Friday in the wake of Thursday's frontal passage. Cooler and drier air will advect into the region from the north in advance of the approaching high. Mostly sunny skies are expected, with high temperatures in the upper 70s and lower 80s. It will also feel considerably less humid, with dewpoints dropping into the upper 50s and lower 60s. High pressure will move offshore and a strong area of low pressure will track across Hudson Bay on Saturday, causing winds to turn out of the south in response. Southerly winds will advect a more humid airmass back into the area, with dewpoints climbing into the upper 60s and lower 70s. Chances for afternoon showers and thunderstorms will accompany the more humid airmass. Both instability and shear values are forecast to remain low, so any storms that do form are expected to stay on the weaker side. Model guidance begins to diverge a bit by Sunday and Monday, but most solutions favor continued above average temperatures, with highs in the mid to upper 80s. Ensemble guidance suggests that chances for afternoon showers and thunderstorms should trend downward as Saturday's system tracks further east across Canada within zonal flow, but there are a few solutions (such as the 12z Canadian) that favor a more amplified longwave pattern and greater chances for showers and thunderstorms. Marine High pressure will result in light northeast winds becoming south through Tuesday. Winds may increase briefly early Wednesday morning as the high shifts offshore, but are more likely to increase in southerly channeling Wednesday afternoon into Wednesday night. Winds shift to the west and northwest and could remain gusty Thursday as a cold front crosses, possibly bringing a few showers and thunderstorms. Sub-SCA (Small Craft Advisory) level north to northwesterly winds are expected over the waters on Friday. Winds will shift to out of the south on Saturday, and could near low-end SCA (Small Craft Advisory) levels within channeled southerly flow Saturday afternoon into Saturday evening. Tides / Coastal Flooding Tide levels remain around 1 to 1.25 feet above normal. With light northeast winds becoming southerly, tide levels are likely to remain relatively steady around 1 foot above astronomical norms through the middle of the week. Annapolis could reach Minor Stage one or two more times through Thursday prior to a cold front shifting winds to the west. Other sites like Havre de Grace, Bowley's Quarters, and Alexandria could approach minor flood at times, as well. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...None. MD...Coastal Flood Advisory until 7am EDT this morning for MDZ014. VA...None. WV...None. Marine None. |
