DISCUSSION
The weather pattern for the next week will be very Spring like with the weather changing from day to day in an active pattern. There'll be some very nice days mixed in with some cooler, showery, windier days.

Today, an upper level low moves across southern Canada quickly and compresses the ridge over the region south. This sets up a stronger pressure gradient and more wind, with the potential for a Lake Wind advisory for Flathead Lake on Sunday. The trailing surface cold front with this system will cause some more showers and a cool down to about 5 degrees below average. There isn't much moisture to work with, so the showers are expected to be pretty light.

Tomorrow through mid-week another ridge builds in with the ridge axis over central Montana. That sets up southwest flow into central Idaho and western Montana. That will bring a warmer, moister air mass to the region with temperatures running 5 to 10 degrees above average through Thursday. Wednesday and Thursday will also have some shower potential, but with the warmer temperatures these will mostly be rain showers.

For the end of the week, models disagree with timing of the next system potentially coming in as early as Thursday afternoon or as late as Friday morning. So far models are showing this as a much wetter system than we've seen recently. Recently we've had some systems bring isolated heavy showers, but this system looks like a closed off low that will be wetter over a much broader area. With the drought across the region, a typical wet system like we normally would get in the late Spring is a welcome sight in the models.

AVIATION
A cold front passing through this morning will cause some showers, especially over the mountains. The main impact of the front will be increased westerly winds today with gusts over 30 kts at frontal passage. Frontal passage is expected this morning and should be through all terminals including KSMN and KBTM by 21/18Z.
