If you happen to be the type of person
that thrives in the heat, you've likely been really enjoying the last seven
days down here in southwest Missouri. For the rest of us, it's been a real
battle just to stay cool! So, what's on tap for the coming work week,
beginning on Monday, July 25?
The good news is that there will be a
cold front heading towards us from up north. The bad news it that it
will have a tough time making it down to the Missouri – Arkansas
border. But, have heart. As the front sags its way into our area on
Monday or Tuesday, we could well see some welcome thunderstorm
activity along with a brief respite from the hellish temperatures. Just how
much relief will depend on how far that old girl sags southwards....
Friday, July22 - If you look carefully on my webpage national map - you'll see that the center of rotation is moving off the the southwest. That would be a good thing!

There's got to be a Sunday
after.....The upper ridge will begin to
retrograde a bit on Sunday, which should allow for a greater
concentration of afternoon thunderstorms along/south of I-44.
Temperatures will be ever so slightly cooler across this area, with
readings in the low to mid 90s. But, slightly higher dew points will
again result in heat indices between 103 and 105. Temperatures north
of the Interstate will again reach the mid to upper 90s.
By early Monday morning, the upper
ridge looks to recenter over the southern High Plains, resulting in
weak/disorganized zonal to northwest flow across the forecast area. A
series of shortwaves moving across the I-80 corridor will push a
synoptic front south into the northern part of Missouri, where it
will stall for much of the coming work week. Nightly MCS (clustered storms) activity will
probably result in some north to south oscillation to the front, as
the boundary is modified by convective outflow and differential
heating.
For the Ozarks, this should result in a
steady diet of scattered thunderstorm activity for much of the week.
Convective potential will likely be centered around 1. the remains of
overnight convective complexes and/or 2. afternoon pulse thunderstorm
activity. Widespread severe weather does not seem likely during this
time period, though any given round of thunderstorms could bring with
it a few marginally severe wind gusts, depending on mesoscale
factors.
This increase in precipitation and
associated cloud cover will help knock temperatures back to around
climatological norms, which are around 90 degrees or so this time of
year.
Long term guidance suggests a pretty
steady state to the overall synoptic pattern through next weekend,
with the upper ridge remaining centered over the southern High Plains
and southern Rockies. [www.taneyservices.com]
