More heavy rain and snow for parts of West

9:45P.M. ET 10/20/2004


Buzz Bernard and M. Ressler, Senior Meteorologists, The Weather Channel




A deep upper-air trough moving slowly from California toward the Four Corner's states is shifting the heavy rain eastward from L. A., San Diego and Las Vegas into Utah and Arizona. Farther north, heavy snow will continue to fall in the mountains of the Interior West, especially in Utah and western Colorado. The heaviest snow is likely in the mountains of southern Utah and the San Juans of Colorado. Only scattered rain and mountain snow showers are expected in the Pacific Northwest and Montana. Meanwhile, most of California, western Nevada and New Mexico should enjoy dry weather on Thursday. Temperatures, by and large, will continue to run below mid-autumn averages from the Rockies west.



More record or near-record heat is expected in eastern and southern Texas Thursday. Elsewhere in the South, maxima will be near to only slightly above seasonal expectations. Overall, highs are forecast to range from the 60s in northern North Carolina to the 90s in eastern and southern Texas (and adjacent parts of Oklahoma and Louisiana). Areas west of the Mississippi will remain dry, while widely scattered showers and thundershowers are expected to dot the southern Appalachians, Alabama, southern Georgia and the Gulf Coast States from southeast Louisiana to Florida. Morning fog may shroud parts of the Tennessee Valley, southern Appalachians and adjacent piedmont areas during the morning.



Cool, cloudy weather will cloak much of the Northeast Thursday, but precipitation should be limited. A little drizzle from an onshore flow may dampen portions of the Middle Atlantic States; and widely scattered showers from an upper-air disturbance may dot western New England, New York, Pennsylvania and New Jersey. Morning fog may also add to the gloom from Lake Ontario southward to West Virginia and western Virginia and the Chesapeake Bay region. High temperatures will range from the 40s in portions of Upstate New York and northern New England to the 60s on the Delmarva Peninsula and in much of Virginia.



Except for a few showers in northern North Dakota and morning fog in the Ohio Valley Thursday, the Great Plains and Midwest should be graced by dry weather. Temperatures will be a bit above average for the season with highs mostly in the 50s, 60s and 70s, north to south. A few readings in the low 80s are possible in southern Kansas and southwest Missouri.
