Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 349 PM EDT Mon Jun 07 2021 Valid 00Z Tue Jun 08 2021 - 00Z Thu Jun 10 2021 ...Persistent heat for the Upper Midwest to the East Coast... ...Continued wet pattern for the south-central states... Portions of the south-central and central U.S. will have multiple rounds of moderate to heavy rainfall that will keep the threat for excessive rainfall and flooding concerns elevated. Parts of northeast Texas, extreme southeast Oklahoma and northwest Louisiana, along with southern Arkansas has been identified by WPC as having a Moderate Risk for excessive rainfall through Tuesday morning. This area will shift north and east through Wednesday morning, focusing over Arkansas, northwest Mississippi, western Tennessee, southwest Kentucky, southern tip of Illinois and southeast Missouri. And over far northeast Arkansas, northern Mississippi, western Tennessee and west/central Kentucky through Thursday morning. In terms of severe weather potential, the Storm Prediction Center has a Slight Risk of severe thunderstorms for Monday and Tuesday across portions of the Northern Plains as a well defined surface low and front intercepts a warm and unstable airmass across this region. Another Slight Risk area is in effect through Tuesday morning for parts of the Southern Plains/Lower Mississippi Valley. Widespread heat will remain in place from the Upper Midwest to the Northeast over the next couple of days. The height pattern associated with this hot airmass is anomalous for early June and is more typical of those in mid-summer. The largest temperature departures will likely occur in South Dakota, where afternoon highs are forecast to reach the mid 90s to low 100s. Additionally, daily maximums in the 90s can also be expected along the Interstate 95 corridor from Washington D.C. to the greater Boston metro area. Stifling heat will continue across the Southwest with western Texas in averaging 100 to 105F. Points to the east will not be as hot thanks to abundant cloud cover and rainfall.
