Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1144 AM CDT Mon Jul 04 2022
Valid 041700Z - 051200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE EASTERN GREAT
The forecast remains on track, and only minor adjustments were made
to the ongoing Critical area based on the latest surface
observations and high-resolution guidance consensus. For details,
see the previous discussion below.
Of note, fuels continue to dry across parts of the southern Plains
where above-average temperatures are forecast. The combination of
hot/dry conditions (minimum RH nearing 25 percent) and breezy
southerly surface winds of 15-20 mph (with higher gusts) could
promote locally elevated conditions generally along and west of the
I-35 corridor in parts of OK and TX. However, these conditions
appear too localized for Elevated highlights.
.PREV DISCUSSION... /ISSUED 0111 AM CDT Mon Jul 04 2022/
A mid-level short-wave trough positioned over the Pacific Northwest
will lift northeast into southwestern portions of Canada, while
another short-wave enters in its wake. Consequently, the broader
upper-level trough situated over much of the West will remain
quasi-stationary throughout the day. Southwesterly mid-level flow
within this regime will remain generally light, but approaching
30-35 kt over portions of the Great Basin.
...Portions of the Eastern Great Basin...
Diurnal heating/mixing will allow for afternoon sustained winds of
15-20 mph and RH values into the teens over a broad region,
extending from southern Nevada into central Wyoming. The region of
strongest winds should be confined to parts of southeast Nevada and
western Utah, where critical highlights are maintained. Elsewhere,
elevated fire-weather conditions will be possible where fuels remain
receptive to large-fire spread.
