Drought Monitor: Dryness Continues Over the West
The following weather summary is courtesy of the U.S. Department of Agriculture and highlights this past week's weather activity.
A cool front brought showers and thunderstorms to the central and northern Plains and Upper Midwest early during this U.S. Drought Monitor (USDM) week, but it weakened as it scraped against high pressure over the eastern U.S., dropping minimal precipitation in the Ohio Valley. Another front brought limited rain later in the period. Tropical Storm Debby inundated Florida with flooding rains beginning Saturday, June 23. Areas of rain peppered the Northeast and Mid-Atlantic States as the fronts limped eastward. An upper-level trough brought waves of rain to parts of the Pacific Northwest and extreme northern Rockies, and small areas of very light convection developed in the Southwest as the summer monsoon tried to get started. Otherwise, upper-level high pressure dominated with hot, dry, and windy weather blanketing much of the West and central Plains. The hot and dry air mass spread eastward as the week progressed. It was a drier-than-normal week for Puerto Rico but the precipitation pattern was mixed for Alaska and Hawaii.
