Daily Weather Summary
June 22, 1999:
As persistent 850 mb high to our NE finally weakens its grip,
850 mb flow will become Srly this afternoon, at around 10 kts.
Therefpre, dewpoints will rise well up into the 60s, and
with the atmosphere more unstable, there will be scattered to
numerous Cu clouds this afternoon, and maybe some widely scattered
thunderstorms. However, most locations will not see any
rain today. High: 90 Low: 68 Mixing hgt.: ~2200 m MSL.
Tomorrow's Forecast
June 23, 1999:
Active weather pattern begins to take shape. Strong 500 mb
shortwave digs into MS River Valley, and in response, surface
pressures fall over Southeastern US. 850 mb southerly flow
increases to around 20 kts by Wednesday afternoon. Also,
with moisture increasing and upward vertical motion, expect
mostly cloudy skies by afternoon with scattered showers and
thunderstorms moving in from the west, becoming more numerous
during the late afternoon and overnight hours. High: 89 Low: 71.
Day after Tomorrow Forecast
June 23, 1999:
850 mb winds become SWly at 20-25 kts, as 500 mb shortwave
slowly approaches from the west. Expect showers and thunderstorms
on Thursday, with cloudy skies.
High: 84. Low: 71.
Outlook
June 25 - 27, 1999:
Uncertainty still with the Friday through Sunday time-frame,
as MRF model cuts off 500 mb low over the region, which would
keep more clouds and good rain chances in the area for Friday
and Saturday, before finally drying out Sunday. However, the
MRF is probably a little slow in getting rid of this low, so
we may dry out some on Saturday. Expect highs to stay in the
85 to 90 range, with lows in the lower 70s.
