***Warm weather continues east of the Rockies***
***Significant snow likely for the Rocky Mountains***
***Storm system develops over the Southern Plains this weekend***
The warm and pleasant spring-like temperatures are forecast to continue
through the weekend for much of the central and eastern parts of the U.S.
with a warm front lifting northward to near the Canadian border. Daily
highs in the 70s and 80s will be commonplace east of the High Plains this
weekend, along with sunny to partly cloudy skies.
Across the northern tier of the country, a cold front dropping southward
out of Canada will bring a fresh surge of colder weather from the northern
Rockies to the Upper Midwest. Moisture from this front is likely to fall
in the form of snow for the higher elevations of the Rockies. By Sunday
night, an upslope snow event is forecast to materialize over Colorado and
into southern Wyoming with moist easterly flow interacting with the
terrain. Several inches of snowfall is likely.
By Saturday evening, a surface low is forecast to develop in the lee of
the Rockies over western Kansas, and this is expected to become the next
big weather maker by the end of the weekend and early next week across the
central U.S. Strong southerly flow ahead of this feature will advect
increasing amounts of moisture northward into the central U.S. ahead of a
strong cold front. This is likely to result in numerous showers and
thunderstorms breaking out from Texas to the Great Lakes for Sunday and
Monday, and severe weather and heavy rainfall are a distinct possibility
with any thunderstorm complexes that develop.
