...Unsettled conditions for the Southwest and New England, and mainly dry
for the Gulf Coast states and the West Coast...
The weather pattern through the middle of the week will continue to be
featured by an upper level ridge across the central U.S., and upper level
lows over both the Desert Southwest and New England. This is an omega
block pattern and is typically slow to change compared to a less amplified
flow aloft. The upper low is forecast to reach the central Plains by
Thursday morning whilst the New England low slowly moves offshore.
In terms of sensible weather impacts, expect scattered to numerous showers
and thunderstorms from Arizona to the central Plains, with the greatest
rainfall amounts likely from eastern Colorado to northern Missouri.
Severe weather will be possible from Texas to Kansas with moisture
returning northward from the Gulf of Mexico, and the Storm Prediction
Center has additional details on that. Temperatures are forecast to be
well below average for the Desert Southwest and southern Rockies, which
can otherwise be quite warm for this time of year.
Across the eastern U.S., temperatures are also expected to be below
average through mid-week compared to early May standards. This will
especially be the case across the Northeast U.S. and the Great Lakes
region, where frost and freeze advisories/warnings are in effect for the
overnight hours. The best prospects for precipitation will be across
Maine where the core of the upper level low will likely reside. Warm and
dry conditions will prevail across the Gulf Coast region with high
pressure in charge of the weather pattern there.
