This Week Has Weather Conditions From All Four Seasons
Published: October 8, 2019
Fall is when the jet stream springs to life from its summer slumber, increasing the chances of snowfall and severe weather. At the same time, the tail end of hurricane season is still in progress.
Occasionally, those weather conditions covering all seasons can happen all at once this time of year, and this week is an example.
Rockies, Northern Plains Snowstorm
Heavy snow and strong winds will develop in the northern Rockies through Tuesday night. The wintry weather will then advance toward the Front Range of the Rockies and northern Plains through late this week.
More than a half foot of snow could pile up in parts of the northern Rockies as well as in the Dakotas and northwest Minnesota through Saturday.
This system will also likely bring the first accumulating snow of the season to the Denver metro area Thursday.

Severe Weather in the Plains
Severe thunderstorms could impact the Plains in the warmer air ahead of the storm system bringing snow to the northern tier states.
Thursday is the most likely day for severe thunderstorms from parts of northern Texas to Oklahoma, eastern Kansas and western Missouri. Damaging winds and large hail are the primary threats, but isolated tornadoes cannot be ruled out.
Watching Areas in the Atlantic
There are no active named storms in the Atlantic, but the National Hurricane Center (NHC) is monitoring a few potential areas for development.
One of those is located well to the east of Bermuda in the central Atlantic and is no threat to land. It has a chance to form into a tropical or subtropical storm through Wednesday before upper-level winds become too hostile.
A separate area is also being watched off the East Coast where low pressure is forecast to form by Wednesday. That low could gradually transition into a subtropical storm later this week, according to NHC.
Even if it doesn't, this system will still impact the mid-Atlantic and Northeast coasts by stirring up rough surf, rip currents and coastal flooding this week. Windy conditions and periods of rain will also impact parts of the coastline during the second half of the week.
Another area of disturbed weather near the Florida coast is also being watched by NHC. The disturbance could undergo some brief development as it moves well off the Southeast coast Tuesday, perhaps merging with the other low off the East Coast later in the week.

Santa Ana Winds Return to Southern California
Santa Ana winds are a common occurrence in fall and they will return to Southern California later this week.
Strong high pressure will build over the interior West by Wednesday. When that happens, Santa Ana winds from the northeast or east move through canyons and passes in Southern California.
The National Weather Service in Los Angeles says a moderate Santa Ana wind event is expected Wednesday night through Saturday morning.
Gusty winds in combination with low humidity will increase the wildfire danger in Southern California if any ignite. Wildfire danger is usually highest in the fall as California's dry season ends.
The same area of high pressure will also bring gusty winds to Northern California, where there will be an increased wildfire danger Tuesday night through Thursday.
