Category: Unseasonably Cool Weather
The new JMA Weeklies are in and highlighted by the following:
- An unseasonably cool close to July
- Worst of the summer heat is behind us
- Warmest anomalies along the East and West Coasts
Week 1:
A trough will sink into the central and eastern portions of the country and result in rather widespread below normal and quite refreshing conditions as we close the month of July. Along with the cool, dry air will come an extended stretch of rain-free conditions through the latter portions of next week.
Week 2:
The JMA suggests the mean trough position will remain across the central portions of the country with signals of ridging developing along the Northwest coast. Cool, wet weather (compared to average) is forecast central as the heat continues across the West. We also note developing warmth across the Northeast region.
Weeks 3-4:
Seasonal temperatures are set to unfold across the central late August with warmest anomalies painting themselves across the Northeast and Northwest portions of the country. The pattern, locally, is set to become more active from a precipitation perspective as wet conditions return.

Highlights:
- Turning more humid this afternoon
- Heavy rain Thursday
- Cooler and drier weekend ahead
Heavy Rain Tomorrow…Wednesday is getting off to a pleasant and beautiful start across the Hoosier state. Sunshine will be with us throughout the day, but our pleasant air mass that we’re awaking to will grow increasingly moist this afternoon and evening. Our next storm system approaches late tonight and will help push widespread rain and thunderstorms across the state early Thursday morning. With such high water content in our air mass, expect periods of heavy rain across the region. Localized flooding will result.
The trade off to the wet and stormy Thursday will be an incredible weekend. Despite a few lingering showers Friday, we’ll notice a dramatic drop in humidity Friday night and this will set the stage for a refreshing last weekend of July. In fact, temperatures will grow cool enough both Saturday and Sunday mornings to perhaps trigger a feel of early autumn for some. Plentiful sunshine can be expected along with unseasonably low dew points with a northeasterly flow in place.
Temperatures and moisture levels will slowly increase as we get into early next week. With the increasing humidity, expect increasing chances of showers and thunderstorms towards the middle of next week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 2.00″ – 3.00″

Highlights:
- Less humid air builds in
- Mid-week storms
- Refreshing weekend
Pleasant Open To The Work Week…High pressure will build overhead today and result in a dry open to the work week. A surface front moved south through the region late last night and north winds will help drier air continue to build in as we move through the day. By this evening, we’ll really feel the more refreshing brand of air.
We’ll remain rain-free through Tuesday before our next cold front approaches late Wednesday into Thursday. Most of Wednesday will remain dry, as well, but we’ll mention chances of a late night thunderstorm arriving from the northwest. Better overall coverage of showers and thunderstorms can be expected Thursday.
Timing is our friend this go around as the front passes Thursday evening, allowing a much drier and cooler air mass to build in. Considering this is the last weekend of July, it’ll feel very, very pleasant.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″ – 1.00″
