By D3/Monday, a mid to upper-level ridge will slowly begin to extend eastward over the Southern Plains, and remain in place over the Southwest. Throughout the rest of the week, and especially by D6/Thursday, heights will begin to fall within the ridge over the northwestern CONUS as mid-level shortwave troughs move atop it. Quasi-zonal flow will transpire from the Pacific Northwest eastward through the Upper Atlantic into most of the extended forecast period. ...Isolated Dry Thunderstorms... A mid to upper-level plume of monsoonal moisture rotating around the ridge D3/Monday will present the opportunity for additional isolated dry thunderstorm chances from the northern to central Rockies, where a drier boundary layer and receptive fuel conditions will reside. Although similar chances are expected D4/Tuesday, increasing moisture through the troposphere should narrow this potential area to a portion of the northern Rockies from western MT, southeastward into western and central WY. ...Wind and RH... Increasing westerly winds will develop across portions of the northwestern Great Basin and Snake River Plain D3/Monday through D5/Wednesday on the northern periphery of the mid to upper-level ridge. The mostly likely time for the highest sustained surface wind speeds appears to be Tuesday into Wednesday via a mid-level jet accompanying a Pacific shortwave trough traversing the northern Rockies, and an increasing surface pressure gradient. Although temperatures will be relatively cooler, a dry boundary layer will remain in place keeping critical minimum RH in present during the afternoons. However, most of these critical weather conditions should overlap with recovering fuels precluding the need for a 40 percent Critical probability area at this time. The exception may be across far northwestern NV. ..Barnes.. 08/03/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more View the full article Quote
