Administrators NorthGeorgiaWX Posted July 25 Administrators Share Posted July 25 SPC Day 3-8 Fire Weather Outlook Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0342 PM CDT Thu Jul 25 2024 Valid 271200Z - 021200Z Fire weather concerns will be focused in parts of the Great Basin and northern Rockies during the extended period. A weak tropical disturbance will move into the Great Basin and eventually the central/northern Rockies this weekend. A second upper-level trough will move into the Northwest early next week and impact the northern Rockies into Wednesday. ...Wind/RH... Strong surface winds are expected in parts of the southern Great Basin on Saturday and perhaps Sunday. Critical fire weather is most likely on Saturday given the stronger mid-level winds and a deeper surface trough. Given the recent lighting activity in the area, fire weather activity could increase with the stronger winds and low RH. Sunday will be similarly dry, but winds will tend to be lighter as the upper trough loses amplitude and the surface pattern becomes more diffuse. Another increase in winds is possible on Monday with the second trough moving into the northern Great Basin. With lower confidence in the upper-level pattern this far in advance, no highlights will be added. Dry and windy conditions appear probable in parts of Wyoming/Montana with the approach of the second trough on Tuesday. As mentioned, the timing intensity of upper/surface features are uncertain enough to preclude highlights. However, with the amount of recent lightning activity, these areas will need to be monitored for an increase in critical fire weather potential. ...Dry Thunderstorms... A tropical disturbance will phase with the mean trough over the Northwest this weekend. This disturbance will move into portions of central and northern Nevada before losing amplitude as it progresses into the northern/central Rockies vicinity. Isolated dry thunderstorm activity is possible in parts of Idaho, western Wyoming, and southwestern Montana on Saturday. Some activity is possible on Sunday as well, but coverage should be less. Thunderstorms will again be possible in the northern Rockies with the second upper-level trough moving into the region Tuesday into Wednesday. Confidence is only low to moderate given the high amount of variability with regard to the upper-level pattern in recent model runs. ..Wendt.. 07/25/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
