Area Forecast Discussion

.SHORT TERM...(Today and tonight)
Issued at 223 AM CDT Mon Jul 1 2019

Details in timing and location of convection remain the biggest
challenge in this broad ridge pattern. Abundant convection extends
from the Dakotas all the way into Wisconsin early this morning passing
along CAPE gradient. Better moisture transport and CAPE values
actually focused more west early this morning and hence, as
convection approaches from the west, seeing less and less
organization.

Airmass remains favorable though for locally heavy rain with
precipitable water values exceeding 2" in moisture rich airmass
that is source region for storms. Plus track of upstream
convection has increased overall flooding threat for much of area.
Flash Flood Watch was issued early this morning to account for
that threat. While storm clusters themselves will remain
progressive, shear number of storms may cause biggest issue.
Confidence in flooding actually materializing is low to medium,
but certainly worth watching for.

How convection plays out later in day is still in question. Skill
in this forecasting has been poor in this pattern. Mesoscale
models remain optimistic that convection will become more
scattered during mid day hours as moisture transport signal
becomes more west to east orientated, or parallel to ridge flow.
This could bring a few dry hours? But then redevelopment is
predicted to reoccur given amount of CAPE residing just to the
south. Location of this will also depend on any boundaries from
convection this morning.

Shear profiles and deep moisture suggest storms later today would
pose mainly a damaging wind and heavy rain potential consistent
with trends past 24 to 48 hrs.

.LONG TERM...(Tuesday through Sunday)
Issued at 223 AM CDT Mon Jul 1 2019

Unsettled pattern continues into mid week, but perhaps some
forecast periods where drier and quiet weather could bring
welcomed break.

On Tuesday, broad upper ridge flattens even more, and with passing
short wave along northern U.S. border, cold front could be pushed
further south. This could bring enhancement of more convection at
some point during the day with unstable airmass residing just to
the south. The good news this boundary could slip far enough south
by Tuesday night to bring a short break in the rain threat.

Later in the week, medium range guidance suggests heights falling
along western states which could bring a return to southwest flow
for central U.S. and more unsettled weather. Hard to pin-point any
details that far out, but storm threats will return certainly.

Even more uncertainty going into next weekend as 01.00z ECMWF
builds upper ridge across central U.S. and associated surface
high. Meanwhile 01.00z GFS passes a wave and actually tries to
develop a drier, northwest flow across western Great Lakes.
Interestingly both solutions suggest drier weather perhaps for the
weekend.

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1132 PM CDT Sun Jun 30 2019

Main aviation concerns are on timing thunderstorms through the
TAF sites. Scattered showers and thunderstorms will move across
the area tonight with the potential for MVFR to IFR conditions
near any storms. Also, the storms will be capable of producing
gusty winds and heavy rainfall. Another round of thunderstorms is
expected across the area by Monday afternon. These storms will
have the potential to produce damaging winds, heavy rainfall and
possible some isolated large hail. Again, MVFR to IFR conditions
should be expected on Monday near any thunderstorms.

&&

.HYDROLOGY...
Issued at 223 AM CDT Mon Jul 1 2019

Repeat rounds of thunderstorms possible next 24 hours, combined
with recent heavy rain, has increased the overall flash flood
threat over much of the area. While storms may remain progressive,
repeat storms over the same location could lead to localized flash
flood impacts. Exact threat area hard to pin-point.
