AREA FORECAST DISCUSSION National Weather Service Raleigh NC 757 PM EDT Sat Jul 4 2020
SYNOPSIS. A weak backdoor front will continue to slowly slide through central NC overnight, but will dissipate Sunday morning. Additional shower and thunderstorm chances are expected across the area Sunday afternoon.
NEAR TERM /THROUGH TONIGHT/. As of 757 PM Saturday .
Isolated showers and storms continue to percolate across the area this evening thanks to modest instability ahead of a weak backdoor front. The majority of the storm activity earlier today was confined to areas north and east of Raleigh where MLCAPE was on the order of 2500 J/KG this afternoon. However additional storms formed on colliding outflows as far away as the NW Piedmont and across the Sandhills. Although there has been an overall decrease in areal coverage of storms since 23Z, there will be at least a continued slight chance of showers and storms area-wide through the remainder of the evening hours given lingering surface based instability. Latest runs of the HRRR depict a rapid decrease in storm coverage after 04Z and I will keep the forecast dry after that point.
Lows tonight will range from the upper 60s to lower 70s, with the coolest values in the northern Coastal Plain. Given rain cooled air and weak onshore flow in these areas, there's a good chance of some cloud/fog development early Sunday morning and I drew in some areas of patchy fog around daybreak.
Overall the forecast is in great shape, only making minor adjustments to near-term grids based on observational trends.
SHORT TERM /SUNDAY AND SUNDAY NIGHT/. As of 400 PM Saturday .
A subtropical ridge in the mid levels will strengthen and expand with associated anticyclonic, subsident flow, amidst and 10-20 meter mid level height rises over cntl NC both Sun and Sun night.
At the surface, an outflow and maritime nely flow-reinforced front, likely with areas of low overcast on the ne/cool side, will extend across cntl NC in the vicinity of I-40 Sun morning. The front will be intersected by a lee trough/low over the wrn Piedmont. Meanwhile, weak, 1016 mb high pressure will extend down and offshore the middle Atlantic coast, with a cooler and more stable air mass expected to extend inland across ern VA and nern NC. Scattered showers and storms will focus along those boundaries with diurnal heating through the afternoon. While convection will again be weekly-steered and sheared, and slow-moving, a high DCAPE environment in excess of 1000 J/kg will favor strong to locally damaging wind gusts.
Otherwise, it will be hot again, with temperatures mostly 90-95 F, and with generally persistence lows in the lwr 70s.
LONG TERM /MONDAY THROUGH SATURDAY/. As of 200 PM Saturday .
The medium-range models develop a low over the Deep South/ARKLATEX by Monday. Otherwise, the flow aloft will be somewhat diffuse, with the aforementioned low slowly drifting east-northeast and amplifying a weak trough before moving east through the region mid- to late- week. However, specifics with respect to the evolution of the low/trough are uncertain, resulting in a lower than normal forecast confidence Thursday onward. At the surface, south-southeasterly flow into the area off the Atlantic will persist, with high pressure to the east and relatively low pressure to the west. There is not very good agreement with the development and subsequent progression of a low developing in response to the low aloft, thus confidence with exactly if and when and how it would impact central NC is low at this time. Regardless of the coverage, still expect shower and thunderstorm activity to be diurnally driven and best chances to be across the southern portions of the area. Temperatures should be within a category or two of normal through the period, with the best chance for below normal highs on the days with more extensive cloud cover and convection. Highs will generally be in the mid 80s to low 90s and lows in the upper 60s to mid 70s.
AVIATION /00Z SUNDAY THROUGH THURSDAY/. As of 757 PM Saturday .
Isolated showers and storms continue across the area this evening with the most vigorous activity around the Triad sites and Rocky Mount. There has been a gradual weakening of storms since about 23Z and this trend should continue for the rest of the night with the loss of daytime heating and instability. Still looks like the best chance of overnight stratus will be in the northeast (RWI primarily) where IFR cigs could develop just before daybreak. Elsewhere, VFR conditions should prevail. Additional showers and storms are expected on Sunday, perhaps a little earlier than what was seen today as there will be a stalled surface boundary across central NC. VCSH introduced at all TAF sites Sunday afternoon except RWI (may be too stable given today's convection).
Outlook: Humid, sely flow off the sw N. Atlantic/Gulf Stream will increase the probability of morning stratus/fog early to mid next week, along with mainly diurnal convection whose coverage may be enhanced by the proximity of a broad and weak area of low pressure in the mid and upper levels of the atmosphere.
