High pressure moves over Missouri from the north. This will bring light surface winds and sunny skies for today. Highs today will be mid to upper 50s.


An upper level wave will continue to shift southeast into the intermountain west region under ridge axis. Ahead of the ridge an upper level wave will begin to move into the Great Lakes region. Overnight lows tonight will be into the lower to middle 30s.


Upper level ridging ahead of the short wave moving out of the southwest will begin to develop through the day Wednesday. Surface high pressure will remain in control however, allowing for another day of lower to middle 50 degree highs.


The upper level low over the southwest will continue to slowly shift eastward into the plains underneath an upper ridge by late Thursday. With the ridge amplifying over the Ozarks region, temperatures across the area will warm into the middle to upper 50s for highs and in the low to mid 30s for lows. This is slightly above normal for this time of year. The atmosphere should remain dry through this period with no precipitation

expected.


By Friday morning, the upper level low will have moved into the southern plains shifting the ridge to the east of the area. This will place the Ozarks under southerly to southwesterly flow and will allow Gulf moisture to begin to make its way into the plains. There remain some differences in the models heading into Friday evening and early Saturday. However, the latest run is more consistent than several of the previous

model runs. The potential for some light rain over the area Friday night into Saturday thus looks possible once again. Will still need to monitor the ultimate track of the system as a farther south track will severely limit rain potential. The cold part of this system will remain to our northeast and we should remain above normal through the 7 day forecast.
