- Better chance for widespread showers and storms Tuesday into Wednesday along with much cooler temperatures.

DISCUSSION

Issued at 210 PM MDT Sun Jun 7 2026

Satellite imagery shows upper trough axis along western Idaho border early this afternoon with deep dry slot across East Idaho. Mid level moisture has largely pushed east into Wyoming, but a few convective build ups remain. Winds have strengthened through the Snake Plain, with gusts exceeding 50 mph in a few locations. Thus will maintain WIND ADVISORY into the evening across the region. Similarly, combination of gusty winds and areas of low humidity remain so will also maintain RED FLAG WARNING. Shortwave axis lifts northeast overnight tonight. Winds decrease with sunset, and tonight should be cool but above any concerns for frost or freeze. After a break on Monday with a rebound in temperatures, the next Pacific shortwave pushes inland. Showers could arrive as early as Monday night, but much of the region should see at least some precipitation Tuesday along with a few thunderstorms. Wetting rains of at least 0.10" are expected for most higher elevation regions. Precipitation continues mainly across the north and northeast into Wednesday. NBM chances of a two-day total of 0.25" exceed 50 percent for the Sawtooths, Frank Church, and most of the eastern highlands north of Soda Springs to the Divide, though most of that total should fall on Tuesday. Temperatures are expected to cool slightly under the influence of the cloud cover and precipitation, and breezy to windy conditions are expected both days. Dry westerly flow is expected for the remainder of the forecast period, with a warming trend and continued breezy conditions.

The 15 to 25 knot sustained winds at the sites will diminish in the 02 to 03Z time frame to 10 knots with gusts subsiding also. VFR will continue through Monday afternoon with winds on Monday much lighter only reaching up to 10 knots at the sites.

FIRE WEATHER

Issued at 306 AM MDT Sun Jun 7 2026

A RED FLAG WARNING continues for Fire Weather Zones 425 and 427 today due to very dry conditions (min RHs of 10-15%) and gusty winds up to 40 mph. Outside of these two zones, we will see near critical fire weather conditions with strong wind gusts up to 50 mph in zone 410 and gusts of 25 to 40 mph elsewhere. Min RHs outside of the Red Flag Warning will range from 15 to 25 percent. Light returns are visible on radar this morning as a cold front works through eastern Idaho this morning though little to no actual liquid precipitation is expected to reach the ground outside of some sprinkles. We should see a break Monday, followed by an increasing chance of showers (with wetting rains) and thunderstorms midweek.
