257 FXUS61 KAKQ 091853 AFDAKQ AREA FORECAST DISCUSSION National Weather Service Wakefield VA 253 PM EDT Sun Mar 9 2025 .SYNOPSIS... Low pressure tracks across the Carolina coast tonight into Monday bringing increasing clouds and chances for light rain showers across southeastern locations. Spring like weather returns on Tuesday. A backdoor cold front crosses the area on Wednesday, bringing cooler weather to coastal areas. Much warmer weather returns late this week. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... As of 250 PM EDT Sunday... Key Messages: - There is an elevated risk for fire spread through this evening across the MD Eastern Shore. - Cool and dry tonight with lows in the mid 30s to 40s. Afternoon wx analysis shows ~1019mb high pressure centered over southern VA and NC, with a strengthening area of low pressure along the central Gulf Coast. Skies are mostly sunny over the area with temps in the 50s and a ~10 mph SW wind (~15 mph with gusts to 25 mph on the eastern shore). With the dry air in place over the area (dewpoints in the upper teens and 20s), RH values have fallen to between 20-30%. This will lead to the potential for some fire weather concerns, especially over the MD Eastern Shore with the slightly higher winds. The SPS for increased fire danger remains in effect for our MD counties until 7 PM. See the fire weather section below for details. For tonight, expect to see cloud cover increase, especially across southern portions of the area, as low pressure tracks ENE to the GA/SC coast along a stalled frontal boundary. The slight uptick in cloud cover combined with a light SW breeze will keep temperatures a bit warmer compared to this morning, with lows generally staying above freezing. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... As of 250 PM EDT Sunday... Key Messages: - Light rain chances increase across far southern portions of the area Monday afternoon into Monday night as low pressure passes to our south. - A taste of Spring returns to the region on Tuesday. - A backdoor cold front crosses part of the area on Wednesday. Temperatures may struggle to get out of the 50s near the coast. The low pressure system is progged to deepen to ~995mb as it tracks NE off the Carolina Coast from Monday-Monday night. Clouds increase across the southern half of the forecast area during the day Monday as a result of the system passing to our south. While widespread rain is expected across NC/SC during the day, dry wx should prevail across the local area through at least midday/early aftn. Light rain may move into NE NC (and perhaps extreme SE VA) by the late aftn/evening. The chance for light rain (PoPs no higher than 40%) continues across far SE VA/NE NC through early Tue AM. Any lingering precip should exit the area by 4 AM Tue. Guidance continues to keep almost all of the precip south of the FA through the event, and will continue with QPFs of 0.10" or less (with no QPF northwest of an Ahoskie-VA Beach line). Highs Monday will generally range from the mid 60s north (due to less cloud cover) to the upper 50s/lower 60s further south. Monday night again sees low temperatures staying above freezing, with lows ranging from the mid 30s NW to the low/mid 40s SE. Broad upper ridging builds the region starting early Tuesday and high pressure will build along the Gulf Coast. Skies should completely clear out Tuesday morning and it likely remains sunny for the rest of the day with light winds. Temperatures on Tuesday are expected to climb above average and will generally be in the lower 70s (upper 50s and 60s closer to the coast/Eastern Shore). The upper ridge axis moves offshore Tuesday night as a backdoor cold front drops toward the area. The front likely pushes through at least E/NE portions of the area on Wednesday before stalling. While this will be a dry FROPA, there will be a rather large temperature gradient across the area on Wed, with 50s (potentially mid-upper 40s) on the cool side of the front (due to NE winds off the cool water) and upper 60s-mid 70s ahead of it. The guidance varies with respect to how far south the front makes it, with the GFS keeping most of the area on the warm side of the front...while the ECMWF and especially NAM are much cooler and show 40s/50s for much of the area. Given the time of year, tend to think that temps will struggle to get out of the 50s at least near the immediate Atlantic coast...but will continue to monitor trends. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... As of 250 PM EDT Sunday... Key Messages: - Dry weather and above average temperatures prevail late this week. - A stronger system potentially impacts the area on Sunday leading to increasing rain chances. The front moves back north on Thursday and temperatures likely rebound a bit with much of the area (minus the Eastern Shore/Northern Neck) seeing highs in the low to mid 70s as the flow becomes southerly. Temperatures warm further Friday into the weekend, with widespread mid to upper 70s currently in the forecast as upper heights rise, high pressure moves offshore, and low-level southerly flow increases. A stronger system likely tracks well to our northwest Saturday night-Sunday. This feature will drag a cold front toward the area, leading to a very good chance for widespread showers across the region. Ensemble guidance shows decent (40-80%) probabilities for >0.50" of rain across the entire area on Sunday. While thunder is not explicitly mentioned in the forecast...will note that some instability will likely be present...especially during the aftn/evening on Sun across E/SE portions of the area. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... As of 135 PM EST Sunday... VFR conditions prevail at all terminals through the 18z/09 TAF period. W-SW winds (with gusts to 20 kt at SBY) will diminish around/after sunset this evening and will then remain light through the remainder of the period. Clear skies outside of high clouds are expected through Mon AM. Outlook: A low pressure system will track to the south/southeast of the terminals Mon-Mon night. Some mid level clouds are possible across SE VA/NE NC, with a 30-40% chc of light rain at ECG Monday aftn-Mon night. Sub-VFR conditions are not expected. VFR/dry conditions return Tue AM and last through the rest of the week. && .MARINE... As of 250 PM EDT Sunday... - Sub-SCA conditions through most of Monday. - Low pressure tracking south of the area brings elevated seas for most of the coastal waters, with elevated winds also for the NC waters. A Small Craft Advisory has been issued for the NC waters Monday night through Tuesday night. - Elevated seas persist into Wednesday due to lingering swell. Occasionally gusty winds are occuring in the northern waters this afternoon as a disturbance aloft moves through and sfc high pressure shifts offshore. However, conditions are sub-SCA and expect gusts to remain at or below 20 kt through this afternoon. Light winds are expected tonight through most of Monday, initially light out of south in the morning, shifting to the SE and then E in the evening and overnight Monday as low pressure tracks south of the area. The low deepens to around 990 mb and makes its closest approach late Monday night and winds should increase to 15-20 kt over the srn coastal waters during this period, with perhaps a brief period of 20- 25 kt S of the NC/VA border between 06z/2 AM and 12z/8 AM Tuesday. Per collaboration w/ MHX to our S, will hoist a Small Craft Advisory for the NC coastal waters from 05z/1 AM Tue-05z/1 AM Wed. This is also due to the potential for 4-7 ft seas. Elsewhere, expecting winds to remain 10-15 kt. Seas are likely to build to at least 4-5 ft for most of the coastal waters, so additional SCAs may need to be issued Monday night- early Wednesday. Winds quickly diminish Tuesday afternoon and become variable in direction, though higher seas linger due to continuing swell from the departing low pressure system. Generally benign marine conditions are then expected for the rest of the week. A backdoor cold front moves through early Wednesday and shifts winds back onshore, but speeds are expected to be sub-SCA. Otherwise, the next chance for widespread marine headlines is not until the weekend as a strong cold front approaches and crosses the area, with the potential for strong southerly flow. && .FIRE WEATHER... As of 250 PM EDT Sunday... There is an elevated risk for fire spread through this evening across the MD Eastern Shore. The combination of relative humidity values of ~30% and winds gusting to 20 to 25 mph will support the potential for rapid spread of any fires that ignite. Elsewhere, RH values remain around 25%, but lower wind speeds (~10 mph) will make conditions less conducive for rapid fire spread. Will continue with the SPS for increased fire danger across the MD Eastern Shore through this evening. && .AKQ WATCHES/WARNINGS/ADVISORIES...
