| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 336pm EDT Wednesday April 8 2026 .WHAT HAS CHANGED... Freeze Warnings and Frost Advisories have been issued where the growing season is active tonight into Thursday morning. Confidence is increasing in near record warmth early next week. .KEY MESSAGES... - 1) Below normal temperatures continue through Thursday morning with Freeze Warnings and Frost Advisories in effect. - 2) A warming trend will take place Thursday and Friday before a cold front drops through early Saturday. - 3) Above normal temperatures, potentially nearing records, and dry conditions are expected early next week. KEY MESSAGE 1...Below normal temperatures continue through Thursday morning with Freeze Warnings and Frost Advisories in effect. High pressure is centered along the northeast coast this afternoon. The orientation will remain fairly similar tonight while gradually tilting eastward. Temperatures are only rising into the 50s this afternoon despite full sun. The airmass will start modifying tonight, but low levels will remain cool and dry. There will be several factors which could influence how efficient radiational cooling is tonight. First, some high level clouds will be spilling into the area. Second, being on the periphery of the high, there may still be a light wind in some places, especially closer to the bay. Third, easterly surface winds will advect some moisture from the Atlantic, with some models developing low clouds east of I-95 and potentially all the way to the Blue Ridge. Given different models handling these features in different ways, did not stray frost/freeze headline decisions too far from blends/ensemble means. The Frost Advisory area in particular probably has the widest range of possible impacts, from safely above freezing with clouds to solidly subfreezing conditions (at least away from the urban centers and tidal shoreline). While some patchy fog could develop as higher dew points advect in, forecast soundings favor low clouds tonight. Frost/freeze headlines remain in effect through 9am Thursday, which temperatures will be quickly warming. KEY MESSAGE 2...A warming trend will take place Thursday and Friday before a cold front drops through early Saturday. Surface high pressure will keep sliding south and east through Friday. Southerly flow at the surface and continued airmass moderation will result in a warming trend. Temperatures will be near normal Thursday and above normal Friday, when many areas will rise into the 70s. However, dew points will remain relatively low Thursday night, especially inland. While multiple outlying areas could drop into the 30s, it appears the most likely location for frost or borderline freeze would be the central Shenandoah Valley. Some patchy fog may also develop as surface dew points continue to rise. Low pressure will pass well to the north Friday, with the trailing cold front dropping south into the area Friday night. Mid level support for the front will be departing to the northeast, and there will be minimal moisture fetch along the frontal zone with largely westerly flow. The greatest chance for any measurable rain will be along the Allegheny Mountains, with perhaps a brief shower or sprinkle to the east. KEY MESSAGE 3...Above normal temperatures, potentially nearing records, and dry conditions are expected early next week. Surface high pressure will quickly build north of the area Saturday before progressing eastward Sunday and offshore through midweek. Aloft, upper level ridging builds over the east coast through the long term period. The departed cold front will only knock down temperatures slightly, remaining above normal for the weekend. Temperatures on Saturday will be in the 60s to 70s, with a gradual warming Sunday. A more dramatic climb will take place Monday through Wednesday, with highs on Tuesday soaring into the 80s to low 90s with only those at higher elevations staying in the 70s. Temperatures Tuesday and Wednesday will approach record values, with very little ensemble spread in this outcome. In addition to gradually warming temperatures, surface high pressure overhead brings primarily dry conditions. Precipitation chances begin returning to the area on Tuesday as a cold front approaches from the Great Lakes region. On Tuesday, precipitation chances stay confined along and west of the I-81 corridor with slightly greater chances areawide on Wednesday, although the frontal position becomes more uncertain by this time. Marine High pressure gradually sliding off the northeast/Mid Atlantic coast will provide light winds through Friday morning. Prevailing winds will be out of the east this afternoon, southeast tonight into Thursday, and then out of the south on Friday. This southerly flow could near advisory criteria on portions of the waters toward Friday evening. A cold front will push south through the area Friday night into Saturday morning. There may be a short period of advisory conditions in northerly flow in the wake of this front. Winds will shift to northeast Saturday night as high pressure slides by to the north. Winds continue to shift to southeasterly Sunday morning as surface high pressure shifts overhead. Winds remain below SCA (Small Craft Advisory) criteria on Saturday before nearing SCA (Small Craft Advisory) criteria on Sunday. Fire Weather Cooler and dry conditions, with greater humidity recoveries and a frost or freeze possible, are forecast through tonight as Canadian high pressure builds over the region. Relative humidity between the teens and lower 30s is occurring this afternoon, but with winds generally around less than 10 mph. Gradual warming and continued dry conditions are expected Thursday and Friday as the high departs. Minimum RH will be in the mid 20s to 30s both Thursday and Friday. Winds will remain light on Thursday, but increase slightly Friday. In particular, the higher ridges could have sustained winds up to 15 mph with gusts of 20 to 25 mph. The next cold front will sink through the area early Saturday, but rain chances are low, and there will be only a small temperature drop behind it. Even warmer conditions are possible early next week. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...Frost Advisory from midnight tonight to 9am EDT Thursday for DCZ001.
