Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 347 PM EDT Sat Jun 21 2025
SYNOPSIS
A prolonged period of very hot weather is expected Sunday through the middle part of next week as a large ridge of high pressure builds over the eastern United States. A risk of showers and thunderstorms returns during the middle to latter portions of the week as a frontal system approaches from the north.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
Surface high pressure is moving off the east coast this afternoon, while a large upper ridge is situated over the mid south. Terrain circulations and bay breeze convergence has led to a few small, brief showers/sprinkles, but they have dissipated as quickly as they formed. With the cu field flattening recently, any chance for additional showers may be dwindling.
Return flow will help increase temperatures and dew points heading into the tonight. Forecast lows should mainly range from the mid 60s to low 70s, while being closer to 75 degrees in D.C. and Baltimore. Mainly clear skies will prevail, with only a few patches of valley fog possible.
SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/
The anomalous mid/upper ridge spreads eastward Sunday and Monday, while the surface high shifts southward. This allows for increasing heat each day. Interestingly, given the position of the ridge, higher dew points may be found rotating clockwise to our north, so it's possible Pennsylvania will have higher dew points than Virginia, at least for Sunday. Air temperatures reach the mid to upper 90s Sunday with heat index values near or above 100 in much of the area. This warrants a Heat Advisory west of the Blue Ridge where criteria is 100. On Monday, air temperatures should tick up slightly more, with upper 90s to around 100 expected. W/NW winds may increase mixing (with the help of downsloping), which would support hotter temperatures and lower dew points, but still resulting in heat index values of 100-110 for much of the area. An Extreme Heat Watch has been issued for northern portions of the area. West of the Blue Ridge, heat index values should easily approach 105. To the east, reaching 110 is a little more uncertain, but it may be close in some areas, so thought it was worth highlighting with a Watch so people can start preparing for what will be an extended period of very hot conditions. Overnights will not offer much relief, with 60s relegated to the higher elevations, and downtown Washington and Baltimore potentially staying in the 80s. For those vulnerable to the heat, please ensure to find ways to stay cool and hydrated, particularly at night. The following website provides more about heat safety: weather.gov/safety/heat.
Overall, the strong ridge should suppress convective development. Terrain circulations and bay breeze convergence could always be the source of a rogue shower/storm, however. SPC also notes outflow from MCSes well to our north could also be a trigger on Sunday afternoon, as depicted in the 12Z WRF-ARW.
Therefore, they painted a broad conditional Marginal Risk for severe thunderstorms that includes northeastern Maryland (meaning storm development is very uncertain, but if they do develop, they could turn locally severe). The only other weather of note through the period is potential for patchy river valley fog during the overnights.
LONG TERM /TUESDAY THROUGH SATURDAY/
A ridge of high pressure will remain in place into at least the middle of next week. Hot and humid conditions are expected during this time. High temperatures are expected to be in the middle to upper 90s each day, possibly reaching the lower 100s in the metros Monday and Tuesday. Heat index values could reach 100 to 110 in many places. Low temperatures at night will be persistently in the middle 70s to near 80. The next chance for showers or thunderstorms is Tuesday afternoon or evening, but an even higher chance of showers and thunderstorms is evident on Wednesday when the ridge of high pressure begins to flatten or weaken. Additional thunderstorm chances remain through the end of the work week as a frontal zone slowly approaches from the north.
AVIATION /19Z SATURDAY THROUGH THURSDAY/
VFR conditions are expected through the weekend and into early next week with strong high pressure in place, although diurnal cumulus development will occur. Winds will be around 10 knots or less, with southerly winds through tonight turning more westerly or northwesterly Sunday and Monday. Can't totally rule out a rogue shower or storm on the bay breeze each afternoon near MTN (as was seen earlier today).
VFR conditions at all terminals Tuesday through Tuesday night. A few restrictions cannot be ruled out on Wednesday given a slight chance for afternoon/evening thunderstorms. Winds northwest 5 to 10 knots through the period.
MARINE
High pressure across the area has kept marine wind gusts mainly at 10 knots or less, with diurnal wind shifts noted.
However, this ridge is moving offshore with southerly channeling picking up later this evening into the overnight hours.
Consequently, gusts up to 20 knots are possible over the Chesapeake Bay with a Small Craft Advisory in effect. A second period of southerly channeling may occur Sunday evening, but it currently looks more marginal and brief. Lighter winds are expected Monday. While unlikely, a rogue shower or storm could pop up along the shore/bay breeze convergence each afternoon.
Sub-SCA winds for Tuesday through Wednesday night. Winds northwest 5 to 10 knots through the period. A slight chance of thunderstorms on Wednesday afternoon/evening could bring brief hazardous conditions to the waters.
TIDES/COASTAL FLOODING
A return to southerly flow will nudge tidal anomalies higher through Sunday. Although flooding is not forecast at this time, some guidance has Annapolis in particular very close to minor flood stage during the evenings this weekend.
