A deep upper-level low pressure system will produce heavy snowfall over parts of the Colorado Rockies today where Winter Storm Warnings and Advisories are currently in effect. Totals may reach a foot in some places. There's an Elevated Fire Risk along the New Mexico-Texas border for today as the pressure gradient tightens and winds pick up east of the Rockies. The surface cold front associated with this system will be the focus for rain and thunderstorms from the Great Plains to the East Coast over the next two days. Some parts of the Upper Midwest and Great Lakes may receive up to 2 inches of rainfall by Wednesday morning. Cold air will continue to filter into the western half of the country today as high pressure expands over the region. High temperatures are expected to be 30 degrees below average in certain areas. California and parts of the Great Basin may be cold enough to break high temperature records today. The threat for heavy snow arrives in the Cascades as a low pressure system dives down the Pacific Northwest coast today. Heavy snow will spread east into the Northern Rockies tomorrow as a new low pressure system dives into the Plains from Canada. Temperatures will continue to rise to near record breaking highs across the Midwest, Northeast and Mid-Atlantic over the next two days ahead of the approaching low pressure system from the West. High temperatures will be up to 40 degrees above average for parts of the Upper Midwest and Northeast today and Tuesday. This anomalous warmth will lead to widespread record breaking temperatures for the Midwest and Northeast. There's likely to be no let-up in the warmth during the evenings as low temperatures are also expected to set records. Heavy rain, thunderstorms and strong winds will impact the Florida Peninsula over the next few days due to Tropical Storm Eta. A High Risk of Excessive Rainfall leading to Flash Flooding is in effect for southeastern Florida while a Slight Risk encompasses most of southern Florida. The most significant impacts from the storm are expected to be felt today as 2-4 inches of rainfall are likely to fall over the Keys and southern Florida. Thunderstorm activity will persist over the Florida Peninsula and Southeast over the next few days. Kebede Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
