DISCUSSION. Rest of Today through Wednesday Night .
Given the upper low and coldest air aloft to our west/southwest, upslope easterly winds, and dry advection in our east (afternoon dew points in the 20s), focus of shower activity into the early evening will be over our western/southern parts, especially the mountains and foothills. There may be enough instability for a few lightning strikes, but overall shower coverage will be less than the past couple days. Showers will all but dissipate tonight. Drier air and less cloud cover will result in a chilly night with a frost or freeze possible for many locations. Patchy fog is also possible in our western zones.
More energy from Canada will drop into the cyclonic flow over our region on Tuesday. Thus, another good chance of showers (and a few weak t-storms) tomorrow afternoon, mainly for west and central parts of our forecast area. Temps on Tuesday should climb to the upper 50s to lower 60s, which is still a bit cooler than normal.
For Wednesday, 500mb heights will begin to rise as we transition out of cyclonic flow. This will lead to warmer temperatures with highs pushing well into the 60s. Progs suggest some instability and short wave energy may again produce some isolated to scattered showers and thunderstorms, mainly over the higher terrain. BT
Thursday through Monday .
The extended continues to show consistency in weak ridging to end the work week, then the ridging breaking down for the weekend. The details however still are murky. Thursday and Friday it still looks confident that some afternoon showers and thunderstorms are possible. There is still some hint at some higher instability working into the area with some moisture flowing in from the Central Plains. There still is not a strong signal for anything particularly organized with this activity. Going into the weekend, the models are all in agreement that a trough will move across the area disrupting the weak ridging. How much moisture will be present across the Northern Rockies remains the big question. The ensembles do not show much in the way of agreement in the precipitation as the wave comes through. Some members have amounts approaching an inch while other have nothing. Have kept slight chance to chance PoPs in through the weekend. Reimer
In general, VFR conditions will prevail through the period. Scattered showers and a few weak thunderstorms can be expected for areas mainly west and south of KBIL this afternoon into the early evening. Local/brief MVFR is possible in these areas. Mountains will be occasionally obscured in show showers and low clouds. STP
