Northwest flow aloft will be over the area through most of the period
with short wave moving through the flow. Upper ridge axis moves
across the area Sun night. Water vapor loop indicated an upper level
short wave was located over northwest ND.

Another upper level trough was located over ALTA. Trough will move
across the area Fri night and Sat morning. Upper level jet will be
south of the area. However a weak low level jet will occur with ALTA
short wave. Moisture increases throughout the column for Fri night.

.LONG TERM...(Monday through Thursday)
Issued at 358 AM CDT Fri Jul 29 2016

Monday to Thursday will see a couple rounds of storms possible as an
active period develops with a couple of strong waves move over the
region in WSW 500mb flow. The first round appears to be moving
across the FA early on Monday with frontal passage occuring in the
morning across the valley...not aligning with peak heating. Severe
storm risk in this scenario would be low...if actual fropa occurs at
current progs. Tuesday will be the day between systems as another
wave moves across the Canadian prairies Wednesday bringing the
threat for storms into the western FA by late afternoon and into the
rest of the area by evening. Temps in this time frame will be
seasonally warm with mid to upper 80s and low 90s through Thursday
