‘Modest’ Relief for Parts of Parched U.S. West
Summary: This U.S. Drought Monitor week saw some improvements along the Eastern seaboard as the first storm of the Atlantic Hurricane season – Tropical Storm Andrea – made landfall over Florida late last week bringing strong winds, heavy rain and thunderstorms to the region. Post-Tropical Cyclone Andrea moved up the East Coast on Friday and Saturday combining with a cold front to deliver heavy precipitation and flooding to the Mid-Atlantic states and New England.
Across the Great Plains, scattered shower activity led to some modest improvements in areas of drought over the eastern halves of Kansas, Oklahoma and South Dakota.
In the Midwest west of the Mississippi, continued shower activity led to improvements in drought areas of western Iowa and southwestern Minnesota.
In the South, modest rainfall led to minor improvements over portions of the Texas Panhandle, central and southeast Texas and northwestern Louisiana.
Out West, unseasonably hot and dry conditions were felt late last week and during the weekend as record-breaking heat gripped Arizona, California and Nevada. Some relief from the heat came to the region late Sunday afternoon and Monday as showers and thunderstorms developed over northwestern Nevada and northern California.
In Alaska, unseasonably warm temperatures, reaching the low 70s, were observed in south-central Alaska; southeast Alaska, the Interior and western Alaska experienced below-normal temperatures.
Looking Ahead: The NWS HPC 5-Day Quantitative Precipitation Forecast (QPF) calls for moderate to heavy precipitation over the Midwest and Northeast while modest rainfall is forecasted across the eastern portions of the Great Plains, Southeast and Pacific Northwest.
The 6-10 day outlooks call for a high probability of above-normal precipitation and below-normal temperatures across New England, the Mid-Atlantic, the Midwest, the northern Great Plains, and the Pacific Northwest. In contrast, a high probability of above-normal temperatures and below-normal precipitation are expected across the Intermountain West, southern Great Plains and the South.
