...THUNDERSTORM THREAT CONTINUES THROUGH MIDWEEK...
.BROADCAST DISCUSSION...High pressure will remain across
the 4 Corners region through the next week. Showers and
thunderstorms will continue each afternoon and evening, especially
across the higher terrain and adjacent valleys through Wednesday.
Humidities will gradually fall for most locations, reaching
critical levels for most valleys by midweek.
.DISCUSSION...High pressure will remain across the Four-Corners
region through the next week. As an upper level low crosses
southern Canada into the northern Intermountain Region through
Monday, sufficient forcing for thunderstorms will continue. As a
result, strong to severe thunderstorms will impact much of
northern Utah this afternoon and evening. The most significant
threat will be strong outflow winds in excess of 60 mph, mainly
north of I-70. For locations south of I-70, strong outflow winds
up to 50 mph and very heavy rain will be the primary impacts from
thunderstorms.
Additional strong thunderstorms will develop Monday afternoon and
evening, but the threat of outflows in excess of 50 mph will
remain closer to the Utah/Idaho border. As high pressure builds
north and east in the wake of the upper level low Tuesday,
thunderstorms will become more confined to the higher terrain and
adjacent valleys through Thursday. A net drying trend will
continue, with most valleys see humidities fall to critical levels
by midweek. Another round of thunderstorms may impact more of the
state as early as Friday as another low pressure area impacts the
Pacific Northwest and pulls moisture from the tropical Pacific
northeastward into the Great Basin.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
