excessive rain is possible in the central part of the state...

Mexico today is expected to spread northward into the central Rockies...

An upper-level vortex forming over the Desert Southwest will promote
unsettled weather to continue across the southern Plains and into the
southern Rockies for the next couple of days. Temperatures will be cold
enough to support wintry precipitation over the higher elevations of
Arizona and New Mexico through tonight, spreading northward into the
central Rockies through Wednesday. Farther to the east, persistent
southwesterly flow aloft ahead of the upper-level vortex will transport
moisture northeastward from the tropical eastern Pacific into the southern
Plains, where rain is expected to fall for the next few days. It appears
that central Texas will see the greatest chance of rain with the
possibility of excessive rain through Wednesday. Temperatures will be 20
to 40 degrees below normal from the southern Plains into the southern
Rockies under persistent clouds and precipitation.
Over southern California, Santa Ana winds reached damaging levels across
parts of the region today. As the high pressure system across the Rockies
gradually weakens, the chance of damaging winds should diminish during the
next couple of days.
After a rainy day across much of the Mid-Atlantic into New England, partly
sunny skies should spread into the area on Tuesday behind a cold front.
Farther west, a colder surge of Canadian air will promote some wintry
precipitation over the upper Great Lakes tonight into Tuesday. By
Wednesday, the wintry precipitation should reach interior New England in
the wake of a cold front.
Elsewhere, the northern Rockies into the northern Plains will remain fine
