MONDAY - MEMORIAL DAY
Some relief is on the way as a surface
high will remain in control of the region's weather through Memorial
Day with temperatures around 80 degrees and mostly sunny skies.
Overall, Monday looks to be a great day for outdoor activities.
TUESDAY
The upper level flow for Tuesday looks to be northwesterly. This is in response to a
ridge that builds just east of the Rockies. Several reinforcing
surface highs will slide out of Canada and across the Plains which
should help to keep rain chances limited. A persistent cut-off upper
low over the Great Lakes may swing pieces of energy through the upper
level flow and bring slight chances for showers and storms between
the surface highs in the form of weak cold fronts. None of this
activity looks severe at this time.
WEDNESDAY
WEDNESDAY
As we head into this afternoon and
early this evening, low level convergence and temperatures warming
into the lower to middle 80s will likely initiate more scattered
thunderstorms from northeastern Kansas into central Missouri. We may
then see widely scattered thunderstorm activity begin to shift
towards the U.S. 60 corridor in the evening as cold pools become
established and that
low level jet begins to redevelop.
The setup for large hail looks good
today given steep mid-level lapse rates, moderate deep layer shear,
and good CAPE/speed shear in the hail growth zone (-10 to -30 Celsius
layer). Inspection of
forecast soundings also indicates quite
a few matches for large hail with the SARS Sounding Analogue System.
With support from indices such as the Large Hail Parameter, we will
include a mention of ping pong ball sized hail in the Hazardous
Weather Outlook.
Given steep low level lapse rates and
relatively high cloud bases, damaging straight line winds also appear
possible in areas where cold pools conglomerate and we get bowing
segments. At this time,
it appears that the greatest threat for
severe storms this afternoon and this evening will be west of U.S. 65
and north of U.S. 60.
THURSDAY
THURSDAY
Remnants of that MCS may then persist
across portions of the central and eastern Missouri Ozarks Thursday
morning. Thunderstorm chances in the afternoon will then be dictated
by convective outflow from morning storms and where that low level
convergence zone ends up. Thursday night and early Friday then look
fairly dry at this point.
FRIDAY - JUNE 3
Friday night into Sunday night, an
upper level trough will dive south towards and into the region
sending a front through the area. This will result in better
widespread shower/storm chances across the region as better lift will
occur.
WEEKEND
Behind the system surface high pressure
and dry conditions will build over the area Sunday into early next
week as highs warm into the 70s each afternoon during this time.... www.taneyservices.com
