KEY MESSAGES

- Strong northerly winds will steadily decline this afternoon, becoming light/variable this evening.

- Below normal temperatures expected through early next week, coldest on Sun-Mon when highs will struggle to reach the freezing mark and morning lows may approach the single digits with wind chill readings as low as 0 to -5F.

- Light accumulating snow possible late Sunday night through mid-day Monday. Light winds, minimal impact(s).

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 1242 PM MST Sat Nov 29 2025

Overview: An upper level wave in British Columbia (today) will dig SSE through the Pacific Northwest (tonight), Intermountain West (Sun) and 4-Corners (Sun night) then progress ESE-E across the Southern Plains (Mon). In the lower levels, 1035-1040 mb Arctic high pressure in the lee of the northern Rockies (today) will slowly shift ESE-SE across the Dakotas and Central Plains (tonight-Sun) then E across the Central MS River Valley (Mon).

Tonight: Strong northerly low-level flow in the wake of an Arctic cold frontal passage this morning will weaken from west to east this afternoon. Breezy N winds will rapidly diminish after sunset. Mostly clear skies, light winds and a newly deposited Arctic airmass (characterized by 850 mb temperatures -8 to -11C) will foster strong radiational cooling. Expect overnight lows in the single digits.

Sunday: With Arctic high pressure situated over the Dakotas and Central Plains.. the Arctic airmass in place over the Tri- State area will persist, unmodified. This.. along with increasing upper level cloud cover / dense high overcast downstream of the upper wave digging SSE through the Intermountain West will foster well below average highs in the mid-upper 20s.

Sunday night-Monday: Expect slightly warmer, albeit still well- below normal temperatures. Guidance continues to indicate a potential for light precipitation (snow) over the region late Sunday night through mid-day Monday.. as the aforementioned upper wave progresses E-ESE from the 4-Corners to the Southern Plains. 12Z 11/29 operational guidance continues to suggest that precipitation coverage, location and amounts will be rather sensitive to the precise track/evolution of the upper wave. Despite inconsistency w/regard to specifics.. guidance has been, and continues to be, in good agreement with regard to the broader/bigger picture -- i.e. a progressive system with relatively low precipitation amounts (light snow accum) in a synoptic setup/pattern that strongly favors light winds. In other words.. minimal impact(s).

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 1255 PM MST Sat Nov 29 2025

Long range guidance suggests a predominantly dry pattern (little potential for precipitation) characterized by a modest warming trend (Tue) as the Arctic airmass exits the region / drains downhill to the east and a low-level southerly return flow pattern ensues.. followed by a cooling trend assoc/w another cold frontal passage mid-week.. followed by a modest warming trend late-week.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1000 AM MST Sat Nov 29 2025

GLD: Scattered to occasionally broken ceilings at ~2,500 ft AGL will abate late this morning. VFR conditions will prevail through the TAF period. Strong (~30-40 KT) northerly winds this morning will decrease to ~25-35 KT during the early afternoon and ~20-30 KT by late afternoon. Winds will further weaken at sunset and become light/variable this evening. Winds will remain light/variable overnight. Winds will shift to the SE and modestly increase to 10-15 KT late Sunday morning.. near the end of the 18Z TAF period.

MCK: Scattered to occasionally broken ceilings at ~2,500 ft AGL remain possible through early afternoon. Otherwise, VFR conditions will prevail through the TAF period. Strong (~30-40 KT) northerly winds this morning will decrease to ~25-35 KT during the early afternoon and ~20-30 KT during the late afternoon. Winds will further weaken at sunset and become light/variable this evening. Light/variable winds will prevail through the remainder of the 18Z TAF period.
