This Week's Drought Summary (2/25)

After a frigid start to the period, especially throughout the middle third of the Nation where daily temperature anomalies were 30 to 40 degrees F below normal and readings dropped below -40 degrees F in Minnesota and 0 degrees F as far south as central Texas, temperatures finally moderated by week's end. By Monday, highs had risen into the 40s & 50s degrees F in the Dakotas and 70s and 80s degrees F in Texas. Frequent Pacific storms battered the Northwest, and then tracked southeastward across the Northern and Central Rockies, dropping plentiful moisture on Washington, Oregon, northern California, Idaho, & western Montana, but missing most of the Southwest yet again. Storms also dropped widespread precipitation on much of the Southeast, mid-Atlantic, and coastal New England while most of the Midwest saw light frozen (snow, sleet, freezing rain) precipitation. Dry weather was observed across much of the Plains except in south-central Texas. Weekly temperatures averaged below to much-below normal throughout the lower 48 States except for central and southern Florida. Readings in Alaska remained below-normal except in the southwest and Aleutians, and significant precipitation was limited to along the southwest, southern, and southeastern coasts. Meanwhile, Hawaii experienced increased shower activity, especially on Kauai where some flash flooding occurred. In Puerto Rico, light showers persisted across eastern sections while the northwest remained mostly dry, and dryness/drought increased.

The ensuing 5 days (March 2-6) expects favorable odds for above normal precipitation across much of Alaska and in the Tennessee Valley and Carolinas. Subnormal precipitation should prevail across the North-Central States (northern halves of the Rockies and Plains and Great Lakes region) an
