Southwest

Weather Underground midday recap for Monday, July 06, 2009.

Unsettled weather persisted in the South on Monday as a stationary font stretched from the Southern Plains to the Mid-Atlantic states. This system was fed with ample moisture from the Gulf, and with warm temperatures allowed for favorable conditions for scattered thunderstorm development. Severe weather has not yet been reported, but periods of heavy rain poured over some areas. In Perry, Florida, 0.78 inches of rain fell in one hour.

To the north, a low pressure system lingered over the Eastern Great Lakes region and triggered light and scattered rainfall. Less than a tenth of an inch of rain fell over New York and the Northeast, but thunderstorms have not yet developed.

Meanwhile, in the Central US, a ridge of high pressure built over the Plains and allowed for mostly sunny skies and warm conditions. Temperatures reached into the mid-80s in most places, while the Southern Plains saw highs in the 90s.

Further west, monsoonal moisture made its way into the Southern and Central Rockies on Monday. This brought cool conditions to the region with highs in the upper 50s and 60s. These storms have turned severe with hail reported in southern Colorado and northern New Mexico and 0.48 inches of rain fell over Los Alamos, New Mexico. To the north, a low pressure system dipped into the Pacific Northwest from British Colombia and triggered cloudy skies with light rain. Otherwise, the rest of the West Coast saw sunny skies and warm temperatures.

Temperatures in the Lower 48 states Monday have ranged from a morning low of 34 degrees at Leadville, Colo to a midday high of 106 degrees at Blythe, Calif.
