| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 331pm EDT Sat Oct 3 2026 .WHAT HAS CHANGED... Have kept precipitation chances higher for those south of I-66. Given extensive cloud cover and continued north to northeasterly flow, have lowered high temperatures for today and Sunday. .KEY MESSAGES... - 1) A frontal system nearby will maintain rain chances through Sunday with below average temperatures. - 2) Frost and freezing temperatures are possible to the west of the Blue Ridge early next week. KEY MESSAGE 1...A frontal system nearby will maintain rain chances through Sunday with below average temperatures. The latest surface analysis places a cold front across North Carolina which stretches southwestward to the Lower Mississippi Valley. As stout high pressure sits across the Great Lakes, a cold air damming (CAD) wedge signature is evident across the local area. In response, mainly northerly flow is occurring which coupled with ample cloud cover is keeping temperatures in the mid 50s to mid 60s. The warmer side of this range is occurring closer to the Mason-Dixon Line where a few cloud breaks are evident on visible satellite imagery. Looking on radar, light rain continues to overrun the surface front. Despite the anomalous moisture in place, the stable nature of the air mass coupled with some low-level dry air has limited rainfall amounts. Hourly totals are not amounting to much more than a trace to 0.05 inches. For those south of I-66, such activity will likely impact these areas through the rest of the afternoon and into the early evening. For tonight, a thick stratus deck remains overhead which will hold overnight lows in the 50s. Some patchy fog is possible, particularly in the more rural low-lying areas. Rain chances do remain just before daybreak Sunday as the next impulse traverses the quasi-stationary front. A band of light rain, perhaps locally moderate in nature, will track northeastward across the region through at least the first half of Sunday. A persistent northeasterly wind should again hold temperatures down in the 60s. Any rain chances should largely come to an end just before sundown Sunday. Overnight conditions should be fairly similar to tonight with lows again in the 50s. As a deep upper trough tracks across far eastern Canada, a more potent cold front sweeps through the northeastern U.S. on Monday. This will favor increasing sunshine, but also a large uptick in northwesterly winds. Afternoon gusts up to 20 to 25 mph are possible, but with highs returning to the upper 60s to mid 70s (upper 50s to 60s in the mountains). KEY MESSAGE 2...Frost and freezing temperatures are possible to the west of the Blue Ridge early next week. A strong area of high pressure will build over the area next week, leading to an extended period of dry conditions. As a cooler airmass works in and high pressure builds overhead, frost and freezing temperatures may be possible to the west of the Blue Ridge both Monday night and Tuesday night. We'll start to see slightly warmer air build in from the south and west later in the week. High temperatures at lower elevations are forecast to be in the 60s (upper 50s/low 60s mountains) on Tuesday, upper 60s to low 70s on Wednesday (60s mountains), and mid 70s (mid-upper 60s mountains) on Wednesday and Thursday. Low temperatures will gradually moderate from the 30s/40s early in the week, to the upper 40s/low 50s later in the week. Marine Northerly winds have finally begun to decrease in strength this afternoon with gusts topping out around 10 to 15 knots. Expect this to persist into Sunday with prevailing north to northeasterly flow given the CAD wedge in place. The true ramp up in wind fields comes for the second half of Monday behind a cold front. Small Craft Advisories will likely be needed midday Monday through the night. Sub-SCA (Small Craft Advisory) level northerly winds are expected on Tuesday. Wind shift to out of the south on Wednesday, and are expected to remain sub-SCA (Small Craft Advisory) in nature. Tides / Coastal Flooding Water levels will be on the decrease as high pressure builds on the northwest side of the front that continues to push south. Another tidal surge is possible going into early next week ahead of the next frontal system. Lots of uncertainty at this time, but some minor tidal flooding looks possible, particularly at the more sensitive locations.
