This hazardous weather outlook is for portions of north and central
New Mexico.

.DAY ONE...Today and Tonight

Near record warmth will dominate northern and central New Mexico
again today, increasing the potential for heat related illness.

A few thunderstorms are possible over and near south central and
southwest mountains this afternoon and evening. Storm motions will
be slowly to the south and southwest.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

An abrupt and major change to much colder, windier and wetter
weather is expected Tuesday through Wednesday. Potentially damaging
winds may develop across parts of eastern New Mexico on Tuesday with
locally strong to damaging east canyon winds affecting parts of the
Rio Grande Valley Tuesday afternoon through Wednesday morning.

Accumulating snow will be possible for parts of north central and
northeast New Mexico Tuesday night through Wednesday although
amounts may be variable due to snowfall rates and the very warm
ground temperatures. A messy mix of precipitation could develop over
portions of northeast New Mexico Tuesday night while an early season
freeze appears likely for portions of central and northeast New
Mexico Wednesday morning and Thursday mornings.

Those with travel plans for tonight through Thursday should keep
