...Threats of severe weather and flash flooding will impact areas from the
Southern Plains to the Southeast today and Monday...
...An increase in snow will occur through the Rockies...
A low pressure system moving through the Southern Plains will be the
primary driver for both the severe weather and flash flooding in the
southern U.S. over the next few days. A cold front is currently moving
eastward across central Texas this morning. This will eventually combine
with a secondary low pressure system and emerging warm front that will
lift north from the Gulf of Mexico during the day today. The merged system
will bring plenty of moisture and instability across Texas as it continues
to slowly progress eastward, reaching the Lower Mississippi Valley
tonight. The best convection is expected to develop along and just ahead
of the cold front. The Storm Prediction Center has placed eastern Texas,
central and northern Louisiana, and far southwest Mississippi in a
moderate risk of severe weather for today through tonight (please check
www.spc.ncep.noaa.gov for more information). There will also be a slight
risk for flash flooding across eastern Texas and portions of the Lower
Mississippi Valley. Flash flood watches are currently in effect along the
Gulf Coast as a result. The low pressure system will then eject
northeastward during the day Monday--pushing the risk of severe weather
and flash flooding eastward as well. The Storm Prediction Center has
outlined much of the Southeast in a Moderate Risk for severe weather for
Monday. In addition, the northward progression of the system will result
in rain and thunderstorm chances for much of the eastern U.S. Monday and
Tuesday.
Another cold front will drop southeast across the Intermountain West and
Rockies over the next couple of days. This will bring precipitation
chances to these regions, with higher elevation snow expected today,
generally in the northern Rockies. As the front progresses southward
tonight and Monday, precipitation will occur throughout the Central Great
Basin and Central Rockies--including higher elevation snow.
Precipitation/snow is expected to increase Monday night into Tuesday,
mainly across Colorado, as a low pressure system develops and intensifies
along the southern extent of the frontal boundary as it pushes across the
Southern Rockies and Southwest.
