Remnant moisture from Odile is still fueling heavy rains in New Mexico and
Texas. A stationary front will remained draped over southeast and central
Texas over the next few days and this will continue to fire off rounds of
convection. The more widespread heavy rainfall will occur through the end
of Thursday night. In fact, WPC has issued a high risk for flash flooding
for southern New Mexico and small portions of the Big Bend through Friday
evening. By Friday, showers and thunderstorms will be more scattered with
the heavier activity concentrating in the Texas Panhandle. Regardless,
much of the southern Plains will have a stormy few days.
A mid-level trough will continue to move over the West Coast through
Thursday night and into Friday. This will bring showers from northern
California and into British Columbia. The precipitation in northern
California will diminish by Friday morning, however the Pacific Northwest
could still see some showers on Friday but will dry out by the evening.
High pressure is beginning to build into the Northeast and New England on
Thursday night in the wake of the cold front pushing offshore. Clear
skies and light winds will settle over the area, bringing cold
temperatures overnight. A frost advisory and freeze warning have been
issued for the Northeast and New England tonight. Behind a front moving
toward the Great Lakes on Friday night will bring cooler, fall-like
conditions to the area.
