…There are Excessive Heat Warnings and Heat Advisories over parts of
Southern California and the Southwest…
…Moisture and the chance for showers and thunderstorms returns to the
Gulf Coast…
The big weather storyline is the continuation of a very hot summer/early
fall for the Southwest U.S. Most of the southern deserts of California and
Arizona are under an Excessive Heat Warning. The Central Valley in
California is also quite hot and Excessive Heat Warnings and Heat
Advisories are in effect. In the southern deserts, high temperatures in
the 100s and even low 110s will be commonplace for the next couple of
days. The Central Valley of California can expect to see highs in the
100s. Remember, heat is the deadliest weather phenomenon in the U.S.!
People spending more time outdoors or in a building without cooling are at
an increased risk of heat-related illness. Visit
www.weather.gov/safety/heat and check local media and government websites
for information on cooling centers.
The Gulf Coast and Florida Peninsula will see the return of widespread
showers and thunderstorms by Thursday and persist into the weekend as
moisture streams northward with an area of disturbed weather in the Gulf
of Mexico. The day 1-3 QPF forecast does allow for some areas to see a
couple of inches of rainfall, but there is not a solid signal in the
models for any localized areas to see excessive rainfall or flooding
threat at least in the short term. However, disturbed weather does look to
persist in the Gulf of Mexico beyond the short term outlook.
Looking across the rest of the nation, a cold front should die out across
the eastern U.S. as it moves through the area, but should hopefully bring
some clearing conditions to a rather soggy Mid-Atlantic and Appalachia for
Thursday. Highs should be pleasant and mildly above average in the middle
70s. A cold front should move out of the High Plains and sweep through
the central part of the country and bring a brief cool down as high
temperatures fall into the 70s. This frontal boundary will aid in gusty
winds and elevated fire danger through this evening. The front will then
progress eastward and bring the chance for showers by Saturday across the
Northeast. The temperatures in the southern Plains and Texas will remain
warm and above average as many locations will see highs in the middle 90s.
Lastly, Friday into Saturday, the Pacific Northwest will see the return of
rain as the next area of low pressure and accompanied cold front enters
the region.
