Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 350 AM EDT Tue May 26 2020

SYNOPSIS.

High pressure will remain just of the eastern sea board through the middle parts of this week. A wave of tropical low pressure will move northward into our region from Florida late Wednesday through Friday. A front will move through our region from the west late Friday and into Saturday. High pressure returns Sunday through early next week.

NEAR TERM /THROUGH TONIGHT/.

A stratus cloud deck is slowly building northward from central Virginia with ceilings dropping below 3000 feet this morning. If the trend continues, the clouds should build into northern Virgina, the eastern Panhandle of WV and western MD over the next few hours but it looks to remain west of the Blue Ridge. Another Stratus deck is slowly spreading westward from the Delmarva peninsula and should spread into our forecast area over the next few hours. Winds continue to be light to nonexistent this morning which has led to patchy dense fog over the Virginia Piedmont. Further areas of fog are developing west of the Blue Ridge in the Potomac Highlands and may become more widespread this morning. Areas that have the stratus cloud deck over them currently have prevented good radiational cooling and limited the formation of fog. If the cloud deck is able to progress into the northern parts of our forecast area this morning, the dense fog threat could be limited. There remains the possibility that a dense fog advisory may be need over the next few hours.

As the sun rises this morning, any fog and low clouds should start to mix out by the mid to late morning periods. Cloud cover is expected to become more scattered in nature by this afternoon Temperatures will trend upwards into upper 70s to lower 80s. Winds should remain out of the east to southeast this afternoon and into this evening. The continue easterly flow and light winds will allow clouds to build over our region again tonight. I can't rule out some patchy fog but may be limited by more widespread cloud cover.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/.

High pressure will remain situated off of the eastern seaboard on Wednesday. A general south to southeasterly flow will form which will start to advect in warm and moist tropical air from the Gulf Stream. A wave of low pressure originating from near Florida where start to track northward toward our region on Wednesday. Ahead of this system, a combination of increasing moisture along with shortwave energy moving northward will lead to the chance for some showers to develop late Wednesday morning and into the afternoon periods. The main threat area for showers will be areas near and south of the DC metro. These showers shouldn't be big rain producers and the thunderstorm threat should be limited to due lack of instability. Daytime temps will hover in the upper 70s on Wednesday.

The wave of low pressure to our south will move into our region late Wednesday and into Thursday. Situ awareness ensembles are indicating anomalous moisture with this system which suggests that moderate to heavy rain will be possible with this low. As PW will be upwards of 1.74 to 2 inches , there will be a threat for localized flooding / flash flooding on Thursday. Increasing daytime temps and moisture during late morning to early afternoon periods on Thursday will prime the environment to be modestly unstable. Models have the potential for 500 to 1500 J/KG of CAPE but shear and forcing will be lacking. Thunderstorms will be possible mainly during peak heating in the afternoon and early evening periods but the severe threat will be limited due to lack of shear and forcing. I can't rule out some isolated instances of strong thunderstorms but I expect the main threat for Thursday to be isolated instances of flooding as PW's are high but low level instability remains weak with this low. The better severe threat will be on Friday as a cold front approaches and moves through our area.

LONG TERM /FRIDAY THROUGH MONDAY/.

Friday is still shaping up to be one of the most active days of the week in terms of convective potential. In an amplified upper flow pattern, ridges will be located over the Atlantic and Desert Southwest, while a closed low in the deep south becomes absorbed by a digging northern stream trough. A surface cold front ahead of the trough will approach but likely won't reach the area during the daylight hours of Friday. However, there will be height falls and a warm/humid/moist airmass in place. Thus, numerous showers and thunderstorms will likely develop with peak heating. While some strong storms are possible, marginal shear and questions about cloud cover/heating could be limiting factors. Localized flooding could be a bigger threat due to precipitable water values of 1.5-2 inches and potential for slow storm motions. However, the lack of a low level forcing feature and weak shear may mean the storms could tend to pulse and propagate by means of cold pool interactions/initiation. The threat may also be dependent on the preceding amount of rain since some areas have been dry lately.

There's some model differences on the timing of the cold frontal passage. Faster solutions would mean Saturday would be dry, while slower solutions would mean a repeat chance of showers and storms. Behind the front, deep troughing will be carved out over the eastern US as strong Canadian high pressure arrives from the northwest. Expect dry weather with low humidity and below normal temperatures for Sunday and Monday.

AVIATION /08Z TUESDAY THROUGH SATURDAY/.

A stratus cloud deck is slowly spreading northward from central Virginia. Ceilings have dropped to MVFR thresholds with these clouds and IFR conditions are expected after 8Z in portions of central and northern Virginia. Fog has developed in areas where the clouds have not reached so far. MRB terminal keeps switching between MVFR and IFR visibilities and LIFR fog will be possible early this morning. CHO terminal has held steady at VFR even with the stratus deck overhead but I expect ceilings to start to drop over the next few hours. A second stratus deck is slowly moving westward from the eastern shore of Maryland. This layer of clouds is expected to overspread the I-95 corridor terminals over the next few hours and ceilings should drop down to MVFR restrictions with the possibility for IFR.

Clouds and fog should start to mix out later this morning with VFR conditions returning for all terminals by early this afternoon. MVFR to IFR conditions will likely return this evening as the easterly to southerly flow continues to bring moisture off of the coast. As winds will become light once again this evening, we can't rule out that fog could form in areas where sky cover isn't as thick. Showers will be possible especially for the CHO terminal on Wednesday. MVFR conditions will be possible on Wednesday as clouds increase ahead of a tropical low pressure wave. More widespread rain will move over all terminals late Wednesday and into Thursday. Rain could be heavy at times and MVFR to IFR conditions are possible on Thursday. Thunderstorms will be possible Thursday afternoon and early evening for all terminals.

Showers and thunderstorms are likely Friday, especially during the afternoon/evening. Then, a cold front will slowly work through the area . if it doesn't clear the area by Saturday, there will be another chance of showers and storms.

MARINE.

No Small Craft Advisories expected today and Wednesday. A wave of low pressure will bring the threat for heavy rain and thunderstorms to all of our waters on Thursday. A southerly flow may lead to the need for Small Craft Advisories on Thursday.

Marginal Small Craft Advisory conditions in south flow may linger into Friday, although the greater hazard will likely be with scattered to numerous thunderstorms, especially during the afternoon and evening. A cold front will then cross the area. If it is slower, more thunderstorms will be possible Saturday; otherwise, northwest flow behind the front may be near advisory thresholds.

TIDES/COASTAL FLOODING.

Anomalies declined further since last evening, and with light winds, no tidal flooding is expected through Wednesday. Winds will increase and turn more southerly Wednesday night into Thursday. Guidance currently is not indicating too much of a surge, though some minor/marginal flooding isn't out of the question toward the end of the week.
