...Active weather pattern continues with heavy rain across the
Plains and Ohio Valley and snow for parts of the Midwest...

The main weather story making weather headlines for the end of the
week will be the continued heavy rainfall and strong thunderstorms
from Texas to the Ohio Valley.  This is in association with a
nearly stationary front that is intercepting copious amounts of
deep moisture from the Gulf of Mexico and leading to multiple
rounds of heavy rain over already saturated soils from eastern
Texas to the Ohio Valley.  A moderate risk of excessive rainfall
continues for many of these areas through Saturday with the
potential for several inches of rain by Saturday morning.  Flash
flood watches are also in effect.

Much of the West will remain in a cold and unsettled pattern
through the end of the week courtesy of multiple shortwaves
dropping south and reinforcing the broad upper level trough of low
pressure.  Snow will spread across the Great Basin and to the
Rockies.  Snow will be heavy at times across the higher terrain in
Nevada, Utah, northern Arizona, and the Colorado Rockies. The cold
airmass in place over the region will keep afternoon highs
generally 10 to 20 degrees cooler than average for late February.
The opposite will be the case for the Deep South and extending
eastward to the Carolinas and Florida, with widespread highs in
the mid 70s to mid 80s with additional record highs expected.
