Today - Wednesday...

Broad easterly boundary layer winds tied to the southeastern CONUS
upper low is tapping into the deep moisture plume affecting SC and
pulling it westward through eastern MO. Expect quite a bit of low
level cloud cover to spread across at least the eastern 1/2 of the
CWA today, gradually reaching the MO/KS border by Monday morning.
Pronounced subsidence under an upper ridge which currently sits over
western MO should ensure a dry forecast with a sprinkle or two
possible over the far eastern counties. Today`s cloud cover will
negatively impact temperatures so have lowered highs over the
eastern 1/2.

The cloud cover will linger through Monday mixing out slowly. While
925mb temperatures will warm 3-5C the northeasterly boundary layer
winds and cloud cover will limit/mute surface heating.

The warmup will be in full bloom Tuesday and Wednesday as the upper
ridge strengthens and southerly winds replace the northeasterlies.
Highs on Wednesday may flirt with 80 degrees in extreme west central

Wednesday Night - Saturday...

Our first good chance at measurable rain arrives on Thursday, which
would mark 20 days without rain. The longest dry stretch (measured
at MCI) this year is 17 days.

As we noted yesterday the medium range models no longer were
tracking an upper low into the Central Plains but instead developed
a northern stream shortwave trough that northwest flow sent it
through the Northern and Central Plains as well as MN/IA on
Thursday. This trend has continued tonight with good spatial and
temporal run-to-run consistency. As a result agree with the model
blend of increasing PoPs for Thursday.

Dry and slightly cooler high pressure will follow the passage of the
cold front early Friday. Since the airmass moving in will be of
Pacific origin the degree of cooling will be minimal with seasonal
temperatures expected.

Low MVFR clouds slowly moved west this morning, and by noon had
spread across most of the terminals in western Missouri. CIGs are
running around 2Kft and the thickness of the cloud cover makes it
look unlikely to dissipate in the near future. Expect cloud cover to
persist through the overnight hours and much of Monday as a result.
Have not included any mention of fog as cloud cover and light
northeast surface winds don`t seem to support the NAM MOS output.
