Heavy snows also possible through the Northern Rockies on Wednesday... ...Much above average temperatures confined to the Southeast and Florida on Tuesday and Florida on Wednesday. Above average temperatures expected from the Pacific Northwest into California over the next two days. Record high temperatures possible Tuesday-Wednesday across Florida.. A cold weather pattern setting up across large portions of the nation over the next two days. This will result in much of the nation from the Rockies eastward to the east having temperatures below average. The core of the cold air will be across the mid section of the nation where record cold temperatures are possible from the Upper Mississippi Valley into portions of the plains. In contrast, much above average temperatures are expected from the Pacific Northwest into California and from the Southeast into Florida. The temperatures across Florida may set records over the next two days for both morning lows and afternoon highs. Along with the cold temperatures across the mid section of the nation, accumulating snows are possible tonight from the lee of the Central Rockies into portions of the Southern and Central High Plains from central to southeast Colorado/northeast New Mexico into the Texas/Oklahoma Panhandle region. A reinforcing shot of cold air will be sinking into the Northern Rockies on Wednesday, accompanied by the potential for heavy snows through the Northern Rockies. After several days of very active weather from the South, northeastward along the east coast, the last vestiges of the recent stormy pattern will be exiting New England tonight as the strong frontal boundary pushes into the Canadian Maritimes. The trailing portion of this front, however, will become stationary across North Florida Tuesday and Wednesday. This will help focus the potential for heavy rains and an isolated chance of flash flooding from far southeast Georgia into North Florida.
