A cold front moved through last night and temperatures will be cooler on Thursday as a result with highs in the low 50s in the valley. West/northwest winds with gusts of up to 25 mph can be expected as well in the valley with gusts of up to 40 mph in the mountains.
A weak disturbance tracking north and east of the area this afternoon will lead to scattered clouds on Thursday afternoon along with a slight chance of brief light showers or sprinkles (snow flurries in the mountains), but most likely we will stay dry with the better chance of showers north and east of Jackson.
Friday morning will start out cold with overnight lows in the mid 20s, but we will warm up to near 60 for a high on Friday afternoon. Another weak disturbance will slide northeast of Jackson on Friday afternoon with a low chance of an afternoon shower or sprinkles (flurries in the mountains), with a better chance farther east over the Togwotee Pass area once again.
High pressure will strengthen over the Western U.S. this weekend, leading to mostly sunny skies and dry conditions on Saturday and Sunday with warmer temperatures also expected, especially on Sunday. An area of low pressure will slowly approach from the west early next week, with showers and thunderstorms developing on Monday afternoon.
