Below normal temps for highs are expected to continue throughout the Desert Southwest for the next couple of days while slightly above normal temps are expected over N NV into UT and portions of CO
General Overview: SIGNIFICANT HEAVY RAIN AND FLASH FLOODING THREAT ACROSS PORTIONS OF THE SOUTH CENTRAL STATES THROUGH THURSDAY, WITH THUNDERSTORMS ALSO POSSIBLE. MIXED PRECIPITATION AND SNOW EXPECTED ACROSS THE PACIFIC NORTHWEST AND NORTHERN ROCKIES. TEMPERATURES WILL REMAIN WELL ABOVE NORMAL ACROSS THE SOUTHERN PLAINS AND LOWER MISSISSIPPI VALLEY, GRADUALLY MODERATING THROUGH THE WEEKEND.
EAST: High pressure will dominate the eastern third of the country today, bringing generally dry conditions to much of the Northeast and Mid-Atlantic. By Friday, a new area of low-pressure will push through the region, bringing rain chances to portions of the Northeast and Mid-Atlantic. The Southeast will see increasing moisture as the week progresses, with rain spreading across the region Friday into Saturday. Some thunderstorm activity is possible along the Gulf Coast states. As we move into the weekend, high pressure returns to the Southeast coast, bringing drier conditions. Rain chances will continue across portions of the Appalachians and interior Northeast through the weekend. Guidance suggests a new area of low-pressure could bring rain chances to much of the region by early next week, with some wintry weather possible for the Northeast.

CENTRAL: Areas of heavy rain and thunderstorms are expected across much of the region today, with flash flooding possible for portions of southwest Texas. As the system progresses eastward, rain will spread across the Mississippi Valley and into the Ohio Valley through Friday. The Central US will see improving conditions by the weekend as high pressure builds in from the west. Another system begins to develop across the Southern Plains by Sunday into Monday, bringing renewed precipitation chances to Oklahoma and Texas, with rain spreading northeastward into the Mid-Mississippi Valley.
