… Flooding potential for the atmospheric river across the
Pacific Northwest and severe weather/flooding potential across the
Southeast should wind down by Sunday…
…Much above average temperatures continue across the Central and
Eastern U.S….
…Critical Fire Weather expected for portions of the Southern
High Plains on Monday…
The risk for flash flooding will dwindle down after today and much
quieter weather should be expected across the Pacific Northwest
and Southeast. Areas in the southern U.S. should be mostly dry for
Monday and Tuesday as high pressure dominates the weather pattern
and the cold front continues to slide southeastward. Florida may
see the chance for rain linger into Monday and Tuesday as the
front is forecast to stall over the region and keep low level
moisture present. The Pacific Northwest will see the frontal
boundary sweep through the area and the cooler, stable air mass
should prohibit any deep moisture plumes, but showers are still
likely off the Pacific. It will be rather cool with highs in the
40s and 50s.
The next big weather storyline is the very warm temperatures
across most of the southern and eastern portions of the country.
Ridging over the Southwest U.S. will keep most of the Southwest
toasty for late December standards with highs in the middle 70s
across California and Arizona and highs nearing or breaking 90
into central Texas. The Southeast will see highs in the 60s and
70s despite a weak cold front passage. Temperatures will begin to
cooldown by the middle of the week.
The Storm Prediction Center has parts of the southwestern Plains
under a Critical Fire Weather Outlook. Conditions will be
favorable for fires as a developing low pressure and frontal
system provide strong,gusty winds atop dry soils. Listen to local
officials on fire weather safety. Moreover, parts of the
Transverse Mountains in California are under an Elevated Fire
Weather Risk with high winds and low relative humidity.
Elsewhere across the nation, a low pressure system will continue
to track northward across the Ohio Valley on Monday and provide
showers and storms along the cold front before exiting the coast
Tuesday. A cold front will be moving though the Rockies and
Intermountain West on Monday and bring the chance for moderate
snow accumulations and gusty winds in areas of terrain. Cooler air
will follow behind the front with highs in the 30s and 20s. The
front will then bring some rain and snow chances to the central
U.S. on Tuesday. Cold air will start to seep into the northern
Plains by the middle of the week as another cold front begins its
march southward.
