Area forecast discussion

a short-wave trough moving through northern Montana has produced
scattered clouds. These clouds will move off to the east by this
evening, after which, high pressure will dominate with generally
clear skies and warming temperatures.
Look for highs around 90 degrees tomorrow with a breezy west wind.
A weak front will move south through the area Monday night with an
increase in clouds but little if any in the way of precipitation.
The best chance for any precipitation would be south of Highway
200. As a result, tuesday's highs will be knocked down into the
70s and 80s and winds will be out of the east at around 10 to 15
High pressure then builds back in with highs Wednesday and
Thursday expected to be in the mid-80s to lower 90s.
A stronger trough looks more likely by the end of the week (late
Thursday into friday), which would help to break down the ridge.
This will bring a better chance of showers and storms to far
eastern Montana. Still a lot of uncertainty with this system this
far out, however.
flight conditions: VFR
Winds: westerly winds at 10 to 15 knots early this evening with
gusts to 25 knots. Then light and variable tonight. Westerly winds
again Monday afternoon at 10 to 15 knots with gusts to 20 knots.
Discussion: a shortwave trough moving through this afternoon has
produced scattered clouds, but these will clear out by this
evening. High pressure moving into the region will then dominate
with dry conditions and just a few clouds.
