...Moderate to heavy snow and below average temperatures likely over
portions of the Southern Rockies/High Plains through early Friday
morning...

...Excessive Rainfall concerns over southeastern Florida for the next few
days...

...Northern tier and West warm up...


A digging upper low will be responsible for the winter storm that impacts
portions of the Southern Rockies/High Plains beginning today. Moisture
advection into the region from the southeast will interact with a weak
surface front as well as the terrain of northern New Mexico and southern
Colorado to produce rain over the lower elevations, a wintry mix in the
highlands and snow in the mountains. Snow levels remain an uncertainty
with potential for accumulating snow as low as 5,500' and as high as
7,500'. Significant rainfall and scattered thunderstorms are also likely
across east, central and southeast New Mexico. Below average temperatures
are expected from southern Colorado to west Texas over the next couple of
days as well.

A stationary front draped across southern Florida will act as a focus for
moderate to heavy rainfall and thunderstorms through the weekend. There's
a Slight Risk (at least 15%) of Excessive Rainfall for portions of
southeast Florida, specifically the greater Miami metro area, where high
rain rates over the urban environment may cause flash flooding over the
next couple of days. A pair of upper-level ridges will support above
average temperatures across much of the West, the Northern Plains, Great
Lakes and Mississippi Valley beginning today.
