Another Round Of Storms Inbound Tonight (Some Strong); Tropics Heat Up; Active Pattern To Close July-Open August…

I. A round of strong (and locally severe) storms blew through north-central parts of the state earlier this afternoon and as we write this, yet another batch of storms is erupting across IL. These storms should hold together into central IN late evening (targeting a 8p-11p arrival west to east) and a few could become severe. Ingredients in place favor strong, damaging wind gusts with the stronger cells, but there’s also the opportunity for a quick spin-up tornado. Torrential downpours can be expected with any and all storms. It’ll be wise to keep tabs on the local radar this evening.

II. As can be expected the deeper into summer we go, the tropics become more active. That’s certainly been the case over the past couple days and all indications continue to point towards a particularly “robust” season as late summer gives way to fall. Interests to the Gulf Coast beaches and Carolina coast should pay close attention to the tropical outlooks in the coming weeks and months. Unfortunately, conditions seem ripe for the opportunity of a few major hurricanes this season, especially when you combine the SST profile with the tendency for the MJO to spend time in Phases 2-3.

In the shorter term, the National Hurricane Center (NHC) is keeping close tabs on the Gulf as well as newly formed TD 7.

III. Overall upper pattern strongly suggests we can expect a very active close to July and open to August. Between next week and the first few days of August, we’re tracking 3 cold fronts that will help to beat back the heat and serve up above normal rainfall through the period (not to mention threat of additional strong to severe storms).

Weekly #AGwx And #Severe Weather Outlook…

I. New heat wave gets underway.

II. Keeping eyes to the sky for periods of gusty storms.

Temperatures will run above average across the eastern half of the country through the period.
Above average rainfall is expected from the Northern Plains into the western Great Lakes and Ohio Valley through the period. The Southeast will run drier than normal.
Specific to central Indiana, we expect 7-day rainfall numbers to be very close to 1″ with locally heavier amounts.
A threat of severe weather is present Sunday (damaging winds are the greatest concern).

Forecast Period: 07.18.20 through 07.25.20

A hot and humid stretch of weather will dominate the upcoming forecast period, including another multi-day stretch with highs in the lower 90s and lows in the lower 70s. The saving grace? Timely rains. After a mostly dry Saturday (only isolated storm coverage expected), more widespread storms are expected Sunday. Some of these could become strong to severe Sunday afternoon, including the threat of damaging winds as a complex moves south through the state. This unsettled theme will continue into the 1st half of the work week with each day offering up scattered showers and storms. Drier air will briefly nudge into the Ohio Valley Thursday and Friday before storm chances return next weekend.

Strong-Severe Storm Potential Late Tomorrow Night Into Predawn Thursday…

High pressure will supply another fantastic day of weather including plentiful sunshine. Humidity levels will remain low today as highs top out in the upper 80s (in case you’re wondering, the average high for July 14th is 85°). Most of our Wednesday will also be nice, but that begins to change Wednesday night…

The Storm Prediction Center includes central Indiana in a ‘marginal’ risk of severe weather both Wednesday and Thursday. This is to account for the potential of a strong-to-severe complex of thunderstorms moving across the state during the overnight period.

This is all thanks to an approaching low pressure system and associated frontal boundary. Eventually, the low pressure system will “wash out” but the boundary will linger in the vicinity, keeping the threat of strong to severe storms across southern and southeastern Indiana during the daytime Thursday.

The vast majority of central Indiana will likely have to deal with thunderstorms late Wednesday night into the predawn Thursday. Given the ingredients in place (50 knot low level jet and dew points that should be approaching 70°) Wednesday night, embedded strong-to-severe thunderstorms are expected. The biggest concerns will be damaging straight line wind potential with these storms.

Forecast radar 4a Thursday.

Locally heavy rain will also be likely as moisture levels rise overnight into Thursday. A quick 1″ of rain can be expected for most of central Indiana with locally heavier amounts where the stronger storms track.

We’ll have more on this and the pattern ahead with our evening video update a bit later. Make it a great Tuesday!

Weekly #AGwx And #Severe Weather Outlook…

I. Heat and humidity builds as we move through the 2nd half of the week.

II. Pattern once again turns active and unsettled mid and late week.

Seasonable temperatures will rise to slightly above normal levels once to mid week, continuing into the weekend. As a whole, the period will run slightly above normal for central Indiana.
The 7-day period should feature above normal rainfall for central Indiana.
We forecast a total of 1″ to 2″ of rain for central Indiana between now and next Sunday with locally heavier totals.

Though the Storm Prediction Center doesn’t currently have a Day 4 severe weather risk highlighted, we need to keep close eyes on this feature for the potential of strong to severe thunderstorms late Wednesday. Large hail and damaging winds are of greatest concern.

Forecast Period: 07.12.20 through 07.19.20

Additional scattered showers and thunderstorms will fire today but shouldn’t be nearly as intense or widespread as what last night delivered. We’ll then welcome a couple of days of cooler, less humid air with dry conditions. Enjoy as the heat, humidity, and storms will return by midweek. In fact, as mentioned above, the potential is present for some stronger storms late Wednesday and it wouldn’t surprise us if the Storm Prediction Center includes portions of the region in a severe weather risk over the next day or two for this threat. This will come on the leading edge of hotter and more humid weather for the 2nd half of the week, continuing into next weekend. As we look longer range (Week 2 time frame), the upper level ridge is expected to retrograde west and open us up to a northwesterly flow aloft. There are strong signals this will lead to a rather busy time of things as we wrap up July, including above to well above average rainfall. Before this takes place, we’re likely looking at another 6-7 day stretch of highs in the lower 90s.
