.DISCUSSION...(Today through next Sunday)
Issued at 309 AM EDT Mon Jun 29 2020

- Dry most of the week

Predominantly dry wx is fcst through most of the
upcoming week. However a few showers and perhaps 
a storm may clip our wsw fcst area early this week. 
This as a result of weak isentropic upglide to the 
ne of the stationary frontal boundary which will 
extend from northern IL se to central/southern IN 
early this week. Low level convergence with the 
lake breeze will also aid this potential each 
afternoon.  

However a consensus of latest medium range 
guidance/ensembles continues to suggest that most of 
the rain and convection will stay to our west/sw/south
in closer proximity to the stationary front. 

- Very warm through the week 

Latest ensembles and medium range guidance continues
to suggest it will be very warm through the week as 
the upper ridge builds in and h8 temps slowly moderate.
High temps will reach the mid to upper 80s daily and 
h8 temps/500 hgts suggest high temps will likely reach
the lower 90s by the holiday weekend. Ensembles also
continue to indicate a very dry pattern will develop 
the next couple of weeks.

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 753 AM EDT Mon Jun 29 2020

We will see scattered showers and thunderstorms affect the western
TAF sites of KMKG, KGRR and KAZO between 3pm and 10p. Otherwise,
we will see some cumulus development especially across the western
half of the state. Winds will be light southeasterly today at 5 to
10 knots. Skies will gradually clear tonight with showers and
storms ending as well. Conditions will mainly be VFR outside of
some brief MVFR/IFR possible in storms this afternoon and evening.

.MARINE...
Issued at 309 AM EDT Mon Jun 29 2020

A high pressure ridge will result in minimal wind speeds 
and wave heights below two feet early this week. Offshore
winds are forecast for the most part but winds will swing
around to the northwest to west around midday daily.
