...Looming tropical threat in the northern Gulf of Mexico...
...Threat of heavy rainfall will begin to ramp up along the central Gulf
Coast...
...Severe thunderstorms possible in the Great Lakes & Southern Plains
today and the Northeast on Thursday...
An area of low pressure will move southwest from the Florida Panhandle
before slowly strengthening over the warm waters of the northern Gulf of
Mexico through Friday while turning more westward. The National Hurricane
Center (NHC) is forecasting a high chance of this system developing into a
tropical depression or tropical storm by Thursday. Please refer to
Tropical Weather Outlooks from NHC for the latest on the status of the
Gulf low. The low should begin delivering some heavy rainfall to the
central Gulf Coast over the next couple days as it drifts slowly west just
offshore the central Gulf coast. Outside of the system's circulation,
record warm low temperatures are possible across portions of the Southeast
and Gulf Coast within a hot and humid summertime air mass.
Another low pressure system moving across the Great Lakes will produce
thunderstorms with heavy rain over the Northern Great Lakes and Midwest
today/Wednesday and the Northeast on Thursday and Friday. Severe weather
is possible with the thunderstorms, with large hail and damaging winds are
the primary hazards. Localized flash flooding will also be possible.
Cooler weather is expected behind an associated cold front, with highs in
the 70s to lower 80s over much of the northern Plains on Wednesday,
western Great Lakes on Thursday, and interior portions of the Northeast on
Friday.
Increasingly hot temperatures are expected across the western United
States with time as the jet stream retreats northward. On Thursday and
Friday, high temperatures in the 90s will be commonplace, with 110s and
perhaps a 120+ reading or two expected in the Desert Southwest.
