Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 315 PM EDT Thu Apr 16 2026
WHAT HAS CHANGED
A Red Flag Warning continues across the area until 7 PM this evening. Any passing high clouds have moved eastward as expected. Otherwise, have added further wording on the late weekend shower threat along with the shift to cooler temperatures on Sunday.
KEY MESSAGES
- Record warmth and elevated to critical fire weather conditions expected this afternoon, with above average tempeatures continuing through Saturday before rain arrives by the night.
- High pressure moves in early next week, with persistent cool temperatures and fire weather risk.
DISCUSSION
KEY MESSAGE 1...Record warmth and elevated to critical fire weather conditions expected this afternoon, with above average temperatures through Saturday before rain arrives by the night.
KEY MESSAGE 1 DESCRIPTION...
As earlier anticipated, high clouds have pushed off to the Eastern Shore while mainly sunny skies are noted over much of the area. Some shallow fair weather cumulus have begun to percolate over the northern Virginia Blue Ridge. Otherwise, minimal cloud cover is evident on the latest GOES-19 visible satellite imagery.
With ample warmth in the lower/middle troposphere, deep mixed layer have unfolded once early morning inversions eroded. Recent aircraft soundings indicate a well mixed environment up to around 800-750 mb. As such, near dry adibatic lapse rates have allowed temperatures to push into the mid 80s to low 90s (per 2 PM observations). The expectation is for these to rise another 2 to 4 degrees given continued heating of the boundary layer. A number of spots should reach the low/mid 90s which again surpasses daily record highs at the climate sites. Once high temperatures for the day have become official, Record Event Statements (RER)
will be issued later today.
Given the degree of vertical mixing in the column, a breezy southwesterly wind could gust to around 20 to 25 mph at times this afternoon, particularly across areas of terrain. The combination of record heat, low relative humidities, and breezy winds atop dried out fuels will yield elevated to critical fire weather conditions today. As such, Red Flag Warnings are in effect until 7 PM from the lee of the Alleghenies eastward across the Shenandoah Valley to the Blue Ridge. Continue to obey local and state burn bans.
Some showers, including a few rumbles of thunder, will start making into the Allegheny Front after dark. However, these should begin to fade as they move eastward overnight. A chance for rainfall east of the Blue Ridge Mountains is around 20 percent with only trace amounts expected. Otherwise, expect continued above average temperatures into Friday and Saturday.
However, no daily records are anticipated as highs fall into the 80s. This does come with a continued elevated fire weather threat.
A large pattern shift occurs for the second half of the weekend as a cold front crosses the region late Saturday night. The degree of convective threat is more limited given the frontal passage is occurring in the middle of the overnight period. The forecast calls for additional shower activity into Sunday as the trough passes by overhead. The combination of extensive cloud cover, passing showers, and cold advection winds will yield highs only in the upper 50s to 60s (40s to mid 50s in the mountains).
KEY MESSAGE 2...High pressure moves in early next week, with persistent cool temperatures and fire weather risk.
KEY MESSAGE 2 DESCRIPTION...
High pressure moves into the area on Monday, allowing for cooler temperatures to persist into early next week. Fire weather still remains a potential concern for Monday as dry, gusty winds persist over the Alleghenies before calming overnight. Relative humidity values are forecast to drop into the upper teens and 20s on Monday, with northwesterly winds potentially gusting to between 20 and 30 mph. High temperatures by then will range between 43F-60F, with lows dipping down into the upper 20s and low 30s overnight into Tuesday morning. Provided that winds are calm by then, frost/freeze could be a concern at that time. Temperatures should gradually warm up later in the week as zonal flow persists at upper levels, with the next precipitation chances coming around midweek as a second potential cold front pushes in from the north.
AVIATION /18Z THURSDAY THROUGH TUESDAY/
A dry forecast is expected at the terminals through tonight. Any attendant showers fall apart once they get east of the Alleghenies. Friday's wind fields shift over to northwesterly behind a weak frontal passage. While a few showers are possible, any direct mention (PROB30) will not be added at this time.
VFR conditions continue into Saturday before showers arrive late in the day with a cold front. This will favor a return to sub- VFR conditions through the night and into Sunday as widespread light showers impact the area. A gusty northwesterly wind is expected behind the front on Sunday.
VFR conditions at terminals are expected on Monday and Tuesday in the wake of Sunday's cold front. Winds will be gusty on Monday, with 15-20 knot gusts expected to persist throughout the day at KCHO and 20-25 knots across all other terminals before decreasing overnight.
Winds shift southerly by Tuesday afternoon.
MARINE
Small Craft Advisories continue through early this evening across most of the waters, while remaining until 1 AM Friday for the far southern waters. Otherwise, gradients weaken on Friday before ramping back up the second half of Saturday.
Southerly channeling effects ahead of a potent cold front will likely require Small Craft Advisories across all waters through Saturday night. Behind this strong cold front, additional advisories are likely needed on Sunday with gusts of around 20 to 25 knots.
Small Craft Advisories are likely on Monday as continued northwest winds flow 15-20 knots. Winds shift southerly on Tuesday as gusts fall below SCA guidelines by the early morning.
FIRE WEATHER
Elevated to critical fire weather conditions are expected this afternoon. Although sustained wind speeds will fall short of criteria, there will certainly be ample opportunity for frequent wind gusts of 20 to 25 mph (possibly near 30 mph at times)
given deep mid-April mixed layers. Otherwise, this is a solid Red Flag Warning event with very dry fuel moistures, high Energy Release Component (ERCs), ongoing moderate to severe drought, record breaking warmth for the month of April, and low RH's will likely offset the lack of strong sustained wind speeds.
Otherwise, elevated fire weather conditions will persist through Saturday due to above normal temperatures, low RH's and little to no rainfall. A wetting rain becomes more likely late Saturday into Sunday, but rainfall amounts are likely not enough to quell a risk of fire weather conditions on Monday. A very dry and gusty northwesterly wind overspreads the area on Monday.
CLIMATE
Many daily records are likely to be broken this week, for both high temperatures and warm low temperatures. Some stations could tie or set their all-time high temperature and warm low temperature records for the month of April.
