.DISCUSSION...
Through Monday night...
A quiet weather pattern for the rest of the weekend and to start
the work week. Upper level energy that pushed a Pacific cold front
through the area has shifted east of the area taking most of the
convection with it. Expect isolated shower activity to linger over
far eastern zones into the sunrise hours as the mid level front
trails the main activity in the Dakotas.
Over the next 48 hours a trof of Canadian origin will drop out of
Alberta and into the northern plains. With cooler cyclonic flow
aloft expect a few showers/weak thunderstorms to develop late this
afternoon into early this evening mainly east of a Roundup to
Billings line. Latest models keep low chances of precipitation
going over the eastern half of the forecast area through tonight
into Monday afternoon as the aforementioned trof transits the
area. There is more moisture remaining over eastern Montana (PWATs
0.75 or better) compared to previous model runs which is enabling
the better precipitation chances. That said any precipitation is
expected to be light in nature (<0.10in). Precipitation chances
end Monday afternoon, with a dry period beginning Monday night
lasting into Thursday morning.
Despite the upper trof transiting the forecast area temperatures
are going to stay seasona this afternoon with highs mainly in the
lower 80s. Monday looks slightly warmer over western zones with
mid 80s there and lower 80s elsewhere. Chambers
Tuesday through Sunday...
Ridge aloft builds quickly over the area Monday night into
Tuesday. This will bring very warm temperatures and dry conditions
to the area Tuesday and Wednesday. Highs each day will be well
into the 90s across the region with triple digits popping up in
some locations.
Another Pacific trof drops in from the northwest on Thursday
afternoon. This will cut temperatures to more seasonal levels for
Thursday and Friday along with bringing back chances for showers
and thunderstorms. Precipitation chances for most areas will be
highest Thursday night, with chances sagging to areas along the
southern state line for Friday. Precipitation accumulations are
forecast in the 0.10 to 0.25 inch range at this point, which is an
increase over the past few days forecasts for this time period.
Ridging builds in behind exiting trof on Saturday boosting high
temperatures toward 90 degrees over central and western zones.
Another period of hot and dry conditions settles in for Sunday
into early next week with afternoon temperatures well into the 90s
again. Chambers
