Area forecast discussion, Jul 24, 4:21 PM EDT, 3 hours 12 minutes before
AREA FORECAST DISCUSSION National Weather Service Raleigh NC 421 PM EDT Fri Jul 24 2020 .SYNOPSIS... An upper level trough and weak surface front will slowly move into the area from the northwest today through tonight. The trough will weaken and move east over the weekend. Upper level high pressure will build back over the area early next week. && .NEAR TERM /TODAY AND TONIGHT/... As of 355 PM Friday... Two areas of showers and storms, one from the SW and one from the SE, will move into the southern Piedmont, Sandhills, and southern Coastal Plain over the next several hours. Despite the clouds and showers this morning, MLCAPE values have still risen to sufficient levels for thunderstorms, 1500-2500 J/kg (highest south). This combined with an upper trough approaching the region from the NW, and PW values near or in excess of 2 inches across the SE half of the region, will result in an environment conducive for showers and storms late this afternoon into the evening. The best chance will be in the south (60-70% POPs) where moisture and instability will be highest. North of there, coverage may remain more scattered, but the HRRR has consistently shown some storms moving across the northern Piedmont later this evening, so will have to monitor this over the next several hours. The primary severe threat with any storms will be damaging winds. They should generally be of the pulse variety, as deep-layer shear is nonexistent. Very heavy rain and localized flash flooding will also be a possibility, especially considering the storms will be slow-moving. Convection will dissipate after midnight with loss of daytime heating. Lows tonight will be in the low-70s. && .SHORT TERM /SATURDAY AND SATURDAY NIGHT/... As of 415 PM Friday... The upper-level trough will move east of the area tomorrow, and moisture should be slightly lower compared to today (PW values about 1.6 to 1.9 inches). As a result, coverage of showers and storms should be slightly lower compared to today, and opted to continue high chance POPs everywhere rather than likely. The best chance for convection is across SE zones where moisture will be greatest. Increasing thicknesses and less cloud cover should result in slightly higher temperatures tomorrow compared to today, generally low-90s, but heat indices should still remain just below Heat Advisory criteria. Any showers and storms will dissipate after sunset with loss of daytime heating. Lows Saturday night will once again be in the low-70s. && .LONG TERM /SUNDAY THROUGH FRIDAY/... As of 310 PM Friday... The first part of next week begins with upper-level shortwave ridging building across central NC from the west on Sunday and lingering to our east through the middle of the week. At the same time, a surface trough will develop along the Mid-Atlantic coast into central NC, and remain across the area through most of next week. Subsidence from the ridge will create higher temperatures each day with highs in the low 90s on Sunday increasing to the mid- 90s by Tuesday. Southwesterly flow at the surface will maintain dewpoint temperatures in the low to mid 70s across the region, helping to increase the heat index to the low 100s for many areas Monday and Tuesday. A Heat Advisory may be needed, however temperatures are borderline at this time. The ridging will mitigate widespread shower/thunderstorm activity on Sunday and Monday, with only isolated to scattered diurnal development expected. An upper-level trough will swing across the region sometime between Tuesday night and Wednesday, increasing precipitation chances Tuesday and Wednesday. This will also help lower high temperatures back to the low 90s for the rest of the work week. Although the trough exits the area mid-week, additional waves will move across the region through the end of the week, keeping precipitation chances higher to close out the work week. The frontal passage mid- week will transport a slightly drier airmass into the Piedmont, lowering dew point temperatures into the mid to upper 60s. Low temperatures will range from the low to mid 70s. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 210 PM Friday... Mainly VFR conditions are expected during the next 24 hours, except where any storms occur this afternoon and possibly some MVFR visibilities in the Triad early tomorrow morning. Scattered cumulus will continue to develop throughout central NC this afternoon, but a lull in precipitation is expected over the next few hours before showers and storms begin to develop. Based on high-res model guidance and the clouds/showers across a good portion of the area this morning, am expecting showers and storms to mostly hold off until after 21z. The best chance for showers and storms will be over southern and eastern parts of the area (FAY and RWI). Where any storms do occur, expect a brief drop in ceilings and visibilities to sub-VFR along with gusty winds, and have included a TEMPO group for this at all TAF sites late this afternoon and evening. Rain chances will lessen considerably after midnight, but based on model guidance and what occurred this morning, there is a chance for mist and MVFR visibilities at INT and GSO once again early tomorrow morning. Looking beyond 18z Saturday: There is a continued good chance of showers and storms tomorrow afternoon and evening, but coverage should be a bit lower than today and more confined to southern parts of the area. Rain chances will be lowest on Sunday and Monday before increasing again on Tuesday and especially Wednesday. While widespread prolonged sub-VFR conditions are not expected, as always, brief drops to sub-VFR are possible in any storms. Patchy sub-VFR stratus and fog are also possible in the early morning each day. && .RAH WATCHES/WARNINGS/ADVISORIES...
