Area Forecast Discussion
National Weather Service Glasgow MT
854 AM MDT Mon Jun 1 2020

Morning update...
Only minor changes to the POP area in and near Petroleum County
for this afternoon, and a cosmetic tweak in temperatures.
Showers/storms will move through the area this evening and
tonight, as noted previously.

Still looking active Friday and beyond. Something to be looked at
for the afternoon package.


Previous discussion...
High pressure settling across the region looks to deliver mostly
sunny skies, seasonably warm temperatures, and dry conditions to
NE Montana for today. However, the next system will quickly spread
increasing cloudiness to the area late this afternoon with
isolated to widely scattered thunderstorms possible this evening
into the overnight hours. The latest 00z HREF ensemble
reflectivity shows the timing of this potential nicely, while the
maximum updraft helicity product shows the need to monitor for an
isolated stronger storm overnight in the SE zones.

High pressure will return dry conditions to the area for the
midweek along with seasonably warm temperatures. That said, longer
range ensemble guidance points to a far more active or unsettled
period to unfold late Friday into the upcoming weekend. It is too
early and speculative to offer much in the way of detail at this
time, but as this period enters the short and medium terms, it
will be worth monitoring this potential next target of


VFR conditions are expected across area terminals for today with
high pressure settled across the region. Winds will be northwest
at 5 to 15 kts.
