.DISCUSSION...(This evening through next Wednesday)
Issued at 225 PM EDT Wed Jul 29 2020

- Isolated showers/storms ending by early evening

Isolated showers will continue to develop across our far se
and far nne fcst areas through mid to late afternoon. An
isolated storm is also possible. However no rain is expected
across the vast majority of our area this aftn and a consensus
of latest high res model guidance suggests that any showers
or storms by early evening will be south to se of our fcst area.
This seems very reasonable given the forecasted cold frontal
position by then.

- Seasonable temperatures through the next week

A consensus of latest medium range guidance and ensembles
continue to suggest temps will average rather close to normal
for this time of year through the next 7-10 day period. Tranquil
wx is fcst as well with dry wx tonight through Saturday. A weak
low pressure system moving ne across the lower Great Lakes region
and upper disturbance moving in from the nw will combine to bring
potential for a few showers Saturday night into Sunday.

However any showers will be light and dry wx is expected for the
vast majority of the weekend. Some clouds and showers are forecast
Sunday night and Monday with the upper trough axis in place. Fair
wx will return for the middle of next week as the upper trough
axis moves east and sfc high pressure ridge takes hold of the wx
pattern.
