…Record heat continues across much of California into the desert
Southwest…
…Elevated to critical fire weather conditions persist across the
Northern to Central Plains…
…One more day of wet weather across the Central Appalachians into the
Mid Atlantic before a drier pattern sets in by mid week…
A mid to upper level ridge is forecast to continue to stretch from off the
California coast, east southeastward across California, the Great Basin
and the desert Southwest over the next few days. This will keep the early
fall heat wave going for much of California into the desert southwest
through the remainder of this week, with widespread moderate to major heat
risk impacts along with potential for widespread record high temperatures.
Excessive Heat warnings are currently in effect across western Arizona,
far southern Nevada and southeast California, while heat advisories
currently stretch along much of coastal California and into the interior
Valleys. These warnings and advisories are currently affecting over 30
million people. High temperatures across these regions are expected to
be 10 to 20 degrees above average over the next few days.
Across the northern tier of the Lower 48 from the Northern Plains into the
Upper Mississippi Valley, the weekend record warm temperatures have been
replaced by cooler weather in the wake of a strong cold front that has
moved out of the Northern Plains into the Upper to Mid Mississippi Valley
and southward into the Central to Southern Plains. This front has not
produced any precipitation across the Northern to Central Plains into the
Upper Mississippi Valley where drought conditions persist. These dry
conditions, combined low relative humidities and gusty winds in the wake
of this front will continue to support a wild fire threat. Red Flag
warnings are currently in effect across much of the Northern to Central
Plains into the Upper Mississippi Valley, affecting approximately 3
millions people.
In contrast to the dry conditions across the western to central U.S., wet
weather is expected to continue across portions of the Central
Appalachians into the Mid Atlantic where a mid to upper level low
continues to move slowly eastward. Additional moderate to locally heavy
rainfall amounts possible across this area into Tuesday. This recent wet
pattern will be coming to an end by Wednesday, as this slow moving system
finally moves off the Mid-Atlantic coast, signaling the beginning of a dry
pattern that will likely last into the weekend.
