Above normal temperatures are expected for most of the Contiguous U.S. over the next two weeks. According to the National Weather Service, probabilities for above normal temperatures exceed 70% from the southern High Plains northeastward across the Central Plains and Upper Mississippi Valley, then eastward across most of the Great Lakes.
In the second week, however, the exception could be in parts of California and Nevada, where above normal temperatures are favored.
Above normal precipitation is favored across the northern tier of the Contiguous U.S. from the Pacific Northwest to the New England coast. Over the eastern third of the country, the favored area of above normal rainfall extends southward to near the Gulf Coast. This is due to several factors, including the trough anticipated near the West Coast, frontal activity, and possible tropical remnants of Barry.
In the second week, below normal precipitation is favored across most of the western CONUS, parts of the Southern Plains northward to the Midwest and the south-central Great Lakes region and the Northeast. Finally, the various models predict significant variability in the Southwest Monsoon. The latest model runs slightly favor above normal precipitation for portions of the Monsoon region during the second week.
Potential evapotranspiration (ability of the atmosphere to remove water from the surface through evaporation and plant respiration) rates will be average to slightly below average over the next two weeks for the Northern Plains while much of the central Great Plains could see slightly higher rates than average.
Over the next two weeks major cattle feeding counties in Texas, Colorado, Kansas, and Iowa, could see higher average temperatures and nighttime temperatures (minimum temps). These departures from average could be in the 1.5 to 2.0 degrees F range. Larger departures will be seen in Midwest in states like Indiana, Wisconsin, and Michigan.
The Northern Plains should see moderate temperatures over the same period.
