Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1028 AM EDT Mon Mar 9 2026
WHAT HAS CHANGED
Slow ridgetop RH recoveries later tonight into Tuesday morning along the ridges. Otherwise, we have extended the Dense Fog Advisory for the central Chesapeake Bay and the Tangier Sound area until 11am. We have cancelled the Dense Fog Advisory for Lower Tidal Potomac and portions of the central Chesapeake Bay and adjacent Patuxent. Fire weather section still has fire weather- specific details, though no hazards are expected to be issued this afternoon.
KEY MESSAGES
- 1) Well above normal temperatures for first half of week.
- 2) A strong midweek cold front will bring a significant drop in temperatures by Thursday, along with gusty winds and widespread shower/thunderstorm chances throughout the region.
- 3) A second cold front could bring additional gusty conditions and persistent cooler temperatures into the weekend.
DISCUSSION
KEY MESSAGE 1..Well above normal temperatures for first half of week.
As of 10am, temperatures are already 5 to 7 degrees above average for early March. We should continue to see temperatures rise through the 60s and into the lower to middle 70s (through the 50s and into the lower 60s in the mountains in the west).
Plenty of sunshine through the rest of the day and again on Tuesday. Temperatures will become above average again on Tuesday, while dry conditions persist. Above average temperatures ahead again for Wednesday. We may be making a run at record high temperatures by midweek. Some daily temperature records look possible (see Climate section below for more information).
KEY MESSAGE 2... A strong midweek cold front will bring a significant drop in temperatures by Thursday, along with gusty winds and widespread shower/thunderstorm chances throughout the weekend.
Minimal change has occurred since prior discussions of hazards expected for this upcoming midweek frontal boundary. A deep upper level trough will result in a strong surface level cold front that will pass through the East Coast, bringing widespread chances for showers and thunderstorms throughout the Mid-Atlantic. Any chances of severe weather will depend on the exact timing of the front passing through the area, with the focus primarily on the region west of the Blue Ridge. CSU learning machine probabilities remain in the 15-30 percent range for all severe hazards within the region, but currently the primary severe-based hazards are gusty winds and heavy rains. Additionally, temperatures will likely drop between 20- 30 degrees overall, bringing some areas potentially below freezing or borderline freezing. Gusty winds between 20-30 knots could result in overall much colder conditions towards the end of this week compared to the beginning of it.
KEY MESSAGE 3... A second cold front could bring additional gusty conditions and persistent cooler temperatures into the weekend.
Once the midweek front passes through, a brief period of calmer conditions will occur early Friday before a second cold front is expected to pass through the region. A low centered over the Great Lakes region will result in a frontal boundary extending southward, resulting in a second period of gusty winds and somewhat reduced potential for rain/showers. Depending on how cool temperatures are by then, this could bring in a chance for wintry/snow precipitation over the mountains. Uncertainty is still high with this event, and additional model runs will help discerning the potential impacts expected with this weekend system.
AVIATION /14Z MONDAY THROUGH FRIDAY/
VFR conditions are expected to prevail through much of Wednesday as sunnier skies return. Clouds increase in coverage late Wednesday ahead of a strong cold front.
Expect periods of sub-VFR conditions across terminals Wednesday night into Thursday, as a strong cold front brings rain showers and thunderstorms to the area. Northwesterly winds with gusts up to 25-35 knots are possible at terminals.
Winds should gradually decrease on Friday before picking back up again, accompanied by a southerly wind shift as another front passes through the region.
MARINE
Sub-SCA winds prevail through Tuesday in a light southerly wind as high pressure builds nearby.
SCA conditions are possible in southerly channeling Wednesday into Wednesday night. Gusts of 20 to 25 kts are possible, especially over the open and middle waters of the bay/tidal Potomac.
A strong cold front is expected to cross over the waters late Wednesday night into Thursday, resulting in gusty north to northwest flow by Thursday. SCA conditions at a minimum are likely, with gusts between 25-35 knots possible over water. Winds will briefly decrease on Friday before picking back up again as a second front passes through, bringing in a southerly wind shift & likely resulting in persistent SCA conditions into the weekend.
FIRE WEATHER
Well above normal temperatures are expected this afternoon through Wednesday, with mostly south to southwest winds across the area. This afternoon looks to be the driest day with minimum RH values of 20-30 percent west of the Blue Ridge, and 30-40 percent to the east. This will be followed by a night of poor RH recovery above 3000 feet, where RH may not recover out of the 30s. Some isolated spots see lower RH values, especially in the valleys out west. Additionally, southwest-facing aspects could see wind gusts up to 20 mph.
Minimum RH values on Tuesday are forecast between 35-45 percent.
Smoke dispersion will be very good to excellent Monday and Tuesday due to increasing transport winds.
A cold front impacts the area Wednesday and Thursday, bringing a potential of gusty winds, wetting rain, thunderstorms, and colder temperatures to finish out the week.
CLIMATE
Daily high records could be tied or set Monday through Wednesday.
Wednesday is the most likely day for warm low records to be tied/set due to cooler air arriving after midnight Wednesday night.
