Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0359 AM CST Fri Dec 29 2023 Valid 011200Z - 061200Z ...DISCUSSION... A progressive upper pattern is forecast through the extended forecast period, with multiple shortwave troughs advancing eastward across the CONUS. A southern-stream shortwave trough should move from northern Mexico and the Southwest across the southern Plains from Day 4/Monday into Day 5/Tuesday. With a cold frontal intrusion expected into the northern Gulf of Mexico, low-level moisture return ahead of this upper trough should remain rather limited. While some potential for mainly elevated thunderstorms is appare…

Fire weather concerns are expected to remain limited for Saturday across the country. Dry conditions will persist across the Southwest into the southern High Plains with afternoon RH minimums expected to fall into the low teens from NM into western TX. Mid-level flow will gradually become more zonal over the southern Rockies through the day, and may result in pockets of elevated fire weather conditions across central to eastern NM.
