Weather Underground Forecast for Thursday, January 10, 2013. A pair of storms will bring active weather to numerous areas of the country on Thursday.
The first storm will begin the day over eastern Texas before moving northeastward toward Illinois by the end of the day. This storm will continue to carry a significant amount of moisture that will produce widespread moderate to heavy rain throughout the Mississippi Valley from Louisiana through southern Wisconsin and Michigan. Several cities in this region could receive several more inches of rain, on top of what has fallen over the past few days. This storm will be relatively warm, thus the precipitation that will fall will be in the form of rain. Slightly farther to the north, however, rain and freezing rain is possible in Minnesota and northern Wisconsin. Flash Flood Watches may remain posted for eastern Texas and Louisiana into the morning from the excess if rain.
The second storm will be quite cold as it moves into the western half of the country. This storm will dump heavy snow from the mountains of California through the Rockies. Winter Storm Warnings and Winter Weather Advisories are posted for many of the higher elevations in the West, warning of up to 3 feet of new snow. The secondary effect of this storm will be due to the cold air that will accompany it. This cold air will bring very cold temperatures for the next several nights. Overnight temperatures for lower elevations of California could plummet into the mid 20s, endangering Winter crops in the Central Valley. Temperatures in the Sierra Nevadas likely to drop below zero for the next several nights, while higher elevations in the Rockies will be even colder.
The Northeast will rise into the 30s and 40s, while the Southeast will see temperatures in the 60s and 70s. The Northern Plains will rise into the 30s and 40s, while the Northwest will see temperatures in the 20s and 30s.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of -18 degrees at Alamosa, Colo. to a high of 123 degrees at Lampasas, Texas
