High Plains as well as portions of the Northeast and Mid-Atlantic on
Friday...

In Florida, ongoing rounds of thunderstorm activity are expected to
continue through Friday before subsiding just in time for the weekend. A
quasi-stationary surface front and upper trough axis swinging through the
Gulf of Mexico/Southeast U.S. will continue focusing tropical moisture
across the Florida peninsula over the next couple of days. Intense
thunderstorms will occur tonight, when storms will bring several more
inches of rainfall, in some cases, over the very saturated and vulnerable
soils/surfaces and urban areas of southern Florida. There is now a High
Risk (at least 70%) of Excessive Rainfall leading to Flash Flooding over
parts of southern Florida, particularly along the I-75 corridor from
Naples to Fort Lauderdale and down to Miami. There remains a Slight Risk
(at least 15%) of Excessive Rainfall across the central-southern peninsula
through Friday, with a Marginal Risk (at least 5%) in place through
Saturday when conditions are likely to improve.
A closed mid-level low will degrade into an open shortwave trough while it
swings through the Southwest and Rockies this weekend. This shortwave
feature will promote thunderstorm activity across the High Plains
beginning Friday afternoon and continuing into the evening. The Storm
Prediction Center issued a Slight Risk of Severe Thunderstorms (level 2/5)
over parts of eastern Colorado, southwestern Nebraska and eastern Kansas.
Scattered severe storms with large hail and severe wind gusts will be
possible along the Front Range into the Central Plains Friday
afternoon/evening. A complex of storms are expected to develop over
western Pennsylvania Friday afternoon and propagate into the
Northeast/Mid-Atlantic Coast that evening.
Tonight, convection is expected to flare up along a cold front pushing
through the Midwest. Surface cyclogenesis along the front could promote
enhanced hourly rainfall rates. Thus, a Slight Risk (at least 15%) of
Excessive Rainfall leading to Flash Flooding is in effect for portions of
the Midwest, from southeastern Iowa/northeastern Missouri across
north-central Illinois and into northwestern Indiana. Totals of around an
inch of rain are expected with isolated amounts closer to two inches
possible in certain spots. Excessive Heat concerns will wane over the
Southwest this weekend as the mid-level disturbance shifts into the Plains
along with an upper ridge. The newly developing ridge over the Central
U.S. will increase Excessive Heat threats across the eastern half of the
country heading into next week.
