An upper level low is currently located over eastern Missouri early this morning. An upper trough is rotating around the low and is moving south across central Missouri early this morning. Ahead of the trough periods of precipitation are develop and
spreading south across the area at times early this morning. Clouds ice is more limited across the area this morning but low level moisture remains in place. As a result periods of drizzle are occurring in the bands of precipitation moving south across the area early this morning. Some cloud ice is trying to spread back into the area with the trough, so a few snow flakes are also mixing in at times. Temperatures are currently in the middle 30s across much of the area and will not drop much more the rest of this morning.
The low level moisture will start to decrease from north to south later this morning into this afternoon as the upper level trough moves south through and out of the area. A break in the precipitation will occur as this occur later this morning into this afternoon. Cannot rule out a sprinkle or flurry but overall most of the area will be dry this afternoon. Highs this afternoon will warm into the upper 30s to around 40 degrees.
The upper level low will continue to rotate and slowly move east today into tonight. Additional upper level energy and lift will rotate around the backside of the low and move south across the region this evening into Friday morning. Cloud ice will
increase across the area with the lift. Temperatures will cool back into the middle to lower 30s this afternoon and evening. Additional bands of light snow will develop and move south this evening into Friday morning. This activity will mainly occur across portions of central Missouri and the eastern Missouri Ozarks where the better lift and moisture will be in place. This snow will occur in bands and not occur in any given
locations all night, but multiple bands could move across the same locations. Highs one Friday will warm into the upper 30s to around 40 degrees.
The upper level low will continue to move off to the east as an upper level ridge moves east over the region this weekend, bringing warmer temperatures into the area. The ensemble model members are then in fairly good agreement in an upper level trough diving south across the region Sunday night into Monday. A drier air mass will be in place and moisture return is limited and as a result the ensemble model members are not indicating any precipitation occurring across the area. Cooler conditions will occur across the northern portions of the area on Sunday and across the entire area on Monday behind the trough. Upper level ridging then builds back over the region behind trough with seasonable temperatures expected into the middle of next week.
