Much of the West will be dry tomorrow, although there will be a couple of exceptions. A weakening Pacific front may bring a few showers to western Washington and far northwest Oregon by late in the day, and a cold upper-air storm will continue to drop snow on the mountains of Colorado and New Mexico, mainly southern Colorado and northern New Mexico. Wind-driven snow, maybe as much as 10 inches in a few spots, will also coat the adjacent high plains of southeastern Colorado and northeastern New Mexico. Meanwhile, strong Santa Ana winds will buffet the mountains, valleys and even coastal plains of Southern California. Gusts could exceed 70 mph in some locations during the morning. Other areas of the Golden State are under frost and freeze advisories for late tonight and early tomorrow. Afternoon temperatures throughout the West will be well below seasonal norms almost everywhere, ranging from the teens in the Rockies to the low to mid-60s along the Southern California coast.



The Southeast will remain dry with seasonable temperatures tomorrow, but a flow of warm, moist air off the Gulf of Mexico in advance of a trough of low pressure will return rain and thunderstorms to portions of the south-central U. S. Wet weather is likely over eastern Texas, much of Oklahoma, Arkansas and northern Louisiana during the morning, spreading into western Tennessee and northern Mississippi during the afternoon. The heaviest downpours are expected over Arkansas. Farther west, the air behind the trough should be cold enough to produce light, wind-blown snow (1 to 4 inches) in the Texas and Oklahoma Panhandles and adjacent parts of northwest Oklahoma. High temperatures will cover a wide spectrum: from the upper 20s in the western portions of the two panhandles to the 80s in far south Texas and southern Florida.



A trough of low pressure extending northward from Texas tomorrow will assist in spreading snow (several inches) over much of Kansas (the southeast corner excepted), southern Nebraska, southern Iowa, parts of northern Missouri and perhaps even portions of central Illinois by late in the day. Meanwhile, rain and showers will dampen southeast Kansas, most of Missouri and southern Illinois. Farther north, sunshine is expected to prevail over the northern Plains and upper Great Lakes. High temperatures in the 30s and 40s will be widespread, although a few spots in western Nebraska and western Kansas might not top 30. On the other end of the balance beam, much of Kentucky will see maxima in the 50s.



Although an active breeze will linger in the Northeast tomorrow, it will diminish steadily from west to east as the day goes on and high pressure builds into the region. The only remaining evidence of today's soaking rain will be a few morning showers dawdling over far eastern Maine. High temperatures will be close to or slightly above average, ranging from the 30s near the Canadian border to the 50s from the southern New England shore southward to Virginia.
