There is a Enhanced Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE MIDWEST THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE UPPER OHIO VALLEY AND MID-ATLANTIC REGIONS SUMMARY Widespread severe thunderstorms are expected this afternoon and evening across parts of the Midwest and Great Lakes region, including far eastern Iowa, northern Missouri, northern/central Illinois, southern Wisconsin, Lower Michigan, and northern Indiana. This includes the potential for widespread/intense damaging winds (some 75+ mph), large hail, and several tornadoes, some of which may be strong to intense. 20z Update The previous forecast remains mostly on track with only minor adjustments made. Across the Midwest, latest GOES imagery shows gradual clearing across southern IA/northern MO/western IL behind a decaying MCS. Surface observations across southern IA show some degree of air mass recovery is ongoing; however, the quality of destabilization with northeastward extent remains very uncertain given more extensive cloud cover, additional precipitation, and the rapid approach of the cold front from the west. Nonetheless, regional 18z RAOBs and VWPs are sampling the approach of a 60-70 knot mid-level jet, which heralds the onset of stronger synoptic ascent across the upper MS Valley. Southerly low-level flow should strengthen through the evening in response to increasing ascent, which will likely help advect higher theta-e air north/northeastward as well as begin to augment low-level SRH. Recent MRMS composites show the onset of convective initiation along the cold front, which should maintain sufficient residence time within the returning theta-e plume for further strengthening over the coming hours. Latest high-res ensemble guidance (including WoFS and time-lagged HRRR/RRFS solutions) appear to be capturing these trends well and continue to depict the corridor of highest severe wind and tornado threat across the Moderate risk zone. As such, little change was made to the ongoing probability and intensity contours. Upper OH Valley/Mid-Atlantic Several loosely organized convective bands have emerged across eastern OH into western PA/NY. Regional VWPs continue to sample deep-layer bulk shear on the order of 15-20 knots, which casts doubt on the eastward extent of the severe wind threat beyond 00-02 UTC when nocturnal stabilization will begin to weaken convection. Recent CAM guidance suggests the peak wind threat should remain across western to central PA/NY, which casts considerable uncertainty on severe wind coverage further east along the Mid-Atlantic coast. Consequently, the 30% wind probabilities have been shifted west to better align with recent observed and modeled trends. (See MCDs #1091 and #1092 for additional details.) Southern Plains Recent surface observations show the cold front rapidly pushing southeast across TX, OK, and southeast KS. Building cumulus is also noted along the front, which suggests convective initiation is probable in the coming hours. These trends align with the previous forecast, see MCD #1090 for additional short-term details.
