30What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, WV wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 7, 2:21 PM EDT, 37 minutes earlier.
Area forecast discussion, Jul 7, 2:21 PM EDT, 37 minutes before
Area Forecast Discussion...CORRECTED National Weather Service Charleston WV 221 PM EDT Fri Jul 7 2017 .SYNOPSIS... Cold front crosses Saturday morning. Cooler and less humid under high pressure Sunday. Unsettled weather returns mid- week. && .NEAR TERM /THROUGH TONIGHT/... As of 157 PM Friday... A series of convective complexes will affect the area this afternoon and tonight. Radar and sfc obs one complex spreading showers and thunderstorms across southeast OH. This activity will likely produce heavy rain and gusty winds up to 40 knots across the northern sections late this afternoon and evening. Models bring a second storm complex dropping southeast, closer to the front, moving into an unstable area. Deep layered shear increases to 50 knots, pwats around 2 inches and sfc CAPE decreasing to 1000 J/Kg suggest storms could reaching severe limits prior and after 00Z tonight. The major threat will be damaging winds. There is a severe thunderstorm watch in effect until 00Z Saturday. The actual cold front crosses the area by 12Z Saturday and exits the eastern mountains by mid morning. Conditions will improve behind the front with drier airmass and high pressure building from the west. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... As of 315 AM Friday... The aforementioned cold front associated with an approaching shortwave axis will move through the southern and eastern portions of the area during the first half of Saturday. Lingering low level moisture and favorable low- to mid-level flow ought to generate scattered showers and perhaps thundershowers during the afternoon Saturday. Upper level subsidence and building surface pressure will clear the area out going into the overnight hours and Sunday. && .LONG TERM /MONDAY THROUGH FRIDAY/... As of 315 AM Friday... Northwest flow associated with an eastern Canadian upper-level low will turn more zonal through the period. Fingers of enhanced vorticity pivoting across the area from the northwest will lead to periodic upticks in PoPs, the most significant coming Wednesday. Long range models are favoring the northern portions of our area for these embedded shots of upper- level energy with modest mountain enhancement. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 145 PM Friday... Radar images show a thunderstorm complex moving southeast across northern to central OH. This complex is expected to reach southeast OH around 20Z, PKB around 21Z and CKB around 21-22Z. Coded brief IFR conditions along the heavier showers. These conditions are developing ahead of a cold front under high instability and enough deep layered shear. Models suggest there will be another batch of showers and thunderstorms along the cold front. Although sfc CAPE will decrease with the FROPA, but deep layered shear increase to about 50 knots. These conditions bring supercell composite parameter to about 5, conducive to severe weather. In fact, a severe thunderstorm watch has been issued for portions of southeast OH and WV until 00Z Saturday. Estimated the timing of storms reaching northern sites and included strong gusty winds. Overall, expect VFR conditions, but MVFR/LIFR along showers and storms through tonight. IFR possible in lingering showers/storms and post frontal stratus into Saturday morning. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Convective winds could be stronger than expected.
