DISCUSSION
As of 1025 AM Wednesday...
KEY MESSAGE 1...Conditional threat of severe weather this afternoon and evening across northern and western counties.
Looking upstream, the current focus is on a line of showers and thunderstorms moving southeast across southern West Virginia. This has prompted a few severe thunderstorm warnings and flash flood warnings in West Virginia; so far the only reports that have come in were of some high water around Charleston. The latest runs of the HRRR show that this line of thunderstorms has more of an eastward component than a southward component, and the line is likely to remain to the north of our area and stay in Virginia. However, the 00Z HRRR has a few members, particularly the ARW and FV3 members, that show the MCS with more of a southerly component, bringing this line into the Triad by 2-4pm. Since the model runs started earlier, they may not have as good of a handle as to the future track of the thunderstorms. While there are currently widespread high clouds across the area, some clearing has begun to occur, temperatures in many locations have already risen into the low 80s, and dewpoints have risen into the low 70s, more moist than in days past. So while there is still reduced confidence as to whether severe weather will occur, the soupy airmass may allow for some stronger thunderstorms to develop. If strong to severe thunderstorms do occur, strong winds would be the primary threat, generally between 2 and 10pm.
KEY MESSAGE 2... Above normal temperatures return today, with unusual and potentially dangerous heat Thu/Fri. The heat may abate a bit Sat, but temps will stay well above normal through Sun.
Surface high pressure centered off the Mid Atlantic coast early this morning will continue to drift toward Bermuda today, allowing warm and humid air to spread into central NC. After mild readings Tuesday, confidence is high that temperatures will return to above normal values today with thicknesses a few m above normal. But the presence of considerable debris clouds from upstream convection, along with scattered late-day storms of our own over the Piedmont prompted in part by a baggy mid level shortwave trough crossing the region, should help curb insolation and keep our highs in the upper 80s to mid 90s. As thicknesses rebound to 10-20 m above normal Thu/Fri, with mid level ridging building behind the trough passage, highs are likely to be in the mid 90s to around 100, hottest Fri.
These highs Thu/Fri may approach or exceed records, and given the added heat stress from warm overnight lows mostly in the 70s, the risk of heat illnesses will increase, and a heat advisory or other heat products may be needed. The NWS experimental probabilistic Heat Risk shows a 70-95% chance of reaching the Major category (level 3 of 4) over almost all of central NC Thu/Fri, indicating that significant adverse health impacts are possible for all populations without adequate cooling or hydration, and heat illnesses may develop suddenly for those working or exercising outdoors during the hottest part of the day. Conditions could be especially dangerous Fri, when an area from the Triangle south to Fayetteville has a 50% chance of Extreme values (level 4 of 4) of Heat Risk. Temps are expected to be slightly lower Sat onward by a category or so as the mid level ridge begins to weaken with a dip in the westerlies into the Ohio Valley, increasing the chance that we'll see greater coverage of mid and high clouds from upstream convection complexes, along with a higher chance of in situ afternoon showers and storms.
But it will still be quite warm and humid, and the heat stress will remain elevated through the weekend and into early next week.
KEY MESSAGE 3... Afternoon and evening thunderstorm chances will continue each day through early next week.
There will be almost daily chances of mainly afternoon and evening pulse-type thunderstorms Friday through early next week. A weakening cold front will move south through much of our region late Friday night and Saturday, stalling over southeastern NC over the weekend.
The next cold front will approach by early next week. The highest probability of showers/storms will most likely be late Friday into Saturday, then again early next week. QPF by the models remains near normal for the period which would be around 1 to 1.25 inch totals for the Friday through Tuesday time frame.
AVIATION /18Z WEDNESDAY THROUGH MONDAY/
As of 125 PM Wednesday...
TAF period: TAFs should be primarily VFR over the next 24 hours. The one exception would be for any showers and thunderstorms that affect INT, GSO, and RDU. A line of showers and thunderstorms has steadily trended southeast across West Virginia into Virginia, and if this line holds together, it might graze INT/GSO, but would have a better chance of reaching RDU. Additional showers and isolated thunderstorms cannot be ruled out either; any precipitation would result in flight restrictions. The potential for showers is not high enough at RWI to include at this time, while no showers are expected at FAY. After sunset, just some scattered low clouds are expected through the nighttime hours into Thursday. Southwest wind with gusts up to 20 kt through the afternoon will remain out of the southwest overnight with gusts coming to an end.
Outlook: The primary chance for showers/storms Thursday afternoon will be around RDU/RWI, although the chance can not be ruled out at other terminals. Diurnally driven showers and thunderstorms will continue through the period, with the highest chance for widespread coverage coming on Monday.
