Issued at 245 PM MDT Sun Apr 6 2025 Troughing /cyclonic flow aloft/ over the central CONUS will be supplanted by an upper level ridge progressing eastward across the Rockies and High Plains Mon-Tue. Expect dry conditions and a warming trend. Near-critical fire weather conditions are possible over portions of the area Tuesday afternoon, when deep vertical mixing could yield 15-25 mph westerly winds. Increasing upper level cloud cover (possibly a thick veil of orographically enhanced cirrus) may affect both insolation and vertical mixing, lending additional uncertainty to an already marginal setup. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... Issued at 245 PM MDT Sun Apr 6 2025 Overview: Cyclonic shear vorticity on the northern periphery of a pronounced westerly upper level jet.. extending eastward from the northern Pacific (35N 155W, or ~1000 mi north of Hawaii) to the central-northern Rockies (~2500 mi).. will rapidly erode/undercut the central CONUS ridge late Tue-Tue night. A transition to NW flow aloft (Wed night-Thu) and N flow aloft (Fri), will follow.. as the Tri-State area finds itself situated between an amplifying western CONUS ridge and an amplifying eastern CONUS trough. Long range guidance suggests that the aforementioned ridge will shift eastward across the central CONUS this weekend.. as an upper level trough amplifies along the Pacific Coast and Intermountain West. Wednesday: Expect dry conditions and above average temperatures. Guidance indicates that breezy WNW winds may develop during the afternoon.. in advance of a modest cold frontal passage (and northerly wind shift) late Wed evening (or Wed night). Low confidence in wind magnitude and timing of frontal passage at this range. Critical fire weather conditions are possible over portions of the area. Thursday: Expect dry conditions and cooler (albeit near- average) temperatures in the wake of a modest cold frontal passage accompanying the transition to NW flow aloft Wed eve- night. Friday: Expect dry conditions and a warming trend as the pronounced western CONUS ridge progresses eastward across the Rockies and High Plains. Saturday-Sunday: Active weather (in some form) will return to the Tri-State area in this period. Expect dry conditions, a warming trend and strengthening wind, on Saturday.. as the upper level ridge departs (progressing east toward the MS River Valley), cyclonic flow aloft envelopes the western CONUS.. and low-level southerly flow strengthens on the eastern periphery of a deepening lee trough/cyclone. Low confidence in forecast specifics at this range. At present, critical fire weather appears to be the primary hazard. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/...
