The upper pattern over the upcoming 7-days will feature a persistent ridge across the West with a trough across the East, tailing back into the South.
It’s a tale of 2 different stories this week from a temperature standpoint: cooler than normal across the East into the southern Plains while heat bakes the northern Plains.
The active pattern will take at least somewhat of a breather to open the new week, locally. The heavy rain/ active storm track will shift south and impact the TN Valley/ Deep South. Wetter than normal conditions are also noted across New England, and monsoonal moisture will plague the Four Corners.
Most central Indiana rain gauges can expect to accumulate between 0.25″ and 0.75″ of rain in the upcoming 7-day period.
Forecast Period: 07.18.21 through 07.24.21
We’ll finally see a period to dry things out to open up the new week. That’s a good thing as we’re running a whopping 3.7″ above normal, month-to-date. High pressure will supply increasing sunshine and eliminate rain chances from our forecast today through Tuesday. Our next opportunity of showers and thunderstorms will come Wednesday as a frontal system scoots through the area. We’ll then get back into a more active stretch as a northwest flow aloft offers up the chance of southeast moving storm clusters to impact our weekend plans. We’ll need to monitor things as we get closer. In addition to a heavy rain threat, this kind of upper pattern has been known to support storm clusters that can also pack strong winds on the leading edge. The other big story this week will be a continued lack of heat. Before we get back to stormy times, the Sunday through Tuesday stretch will truly feature “chamber of commerce” type weather by late-July standards. Get out there and enjoy!
The upper level pattern this week will feature troughiness in the central portion of the country while a significant high pressure ridge continues to bake the Northwest with unseasonably hot, record-breaking temperatures.
Record heat will continue to bake the Northwest while unseasonably cool temperatures will be welcomed into the Front Range, southern Plains, and along the Gulf Coast.
We forecast widespread rainfall amounts between 1.5″ and 2.5″ across central IN in the upcoming 7-day period, but there will be locally heavier totals.
Well above normal precipitation can be expected ahead through the period from the southern Plains into the Great Lakes, TN Valley, and Mid-Atlantic.
While ingredients aren’t in place for a widespread severe weather event, one or two cells could pulse to severe levels later this afternoon across the northern half of IN, including an isolated tornado, given the parameters.
Forecast Period: 06.27.21 through 07.04.21
A frontal boundary will remain draped across the general area through the middle part of this week. While subtle differences will remain regarding greatest concentration of shower and thunderstorm coverage each day, it’s a safe bet most of the region will see a passing shower or storm at some point each day this week. We’ll keep an eye on radar trends this afternoon for the possibility of a local severe weather warning (threat is primarily going to be centered on western and northern parts of the state). Eventually the front will get shoved south and we’ll welcome in drier, cooler air as we get ready to kickoff the long Independence Day weekend. In fact, overnight lows will likely fall into the lower 50s for some by the weekend with highs only in the low-mid 70s. Rain chances will persist Friday and Saturday before we dry things out in earnest for the holiday, itself.
The mean upper pattern in the week ahead will feature a trough across the Great Lakes into the Ohio Valley with the hot dome remaining in place across the Four Corners.Temperatures will run below to well below normal across the upper Mid West south into the Southeast states this week. Meanwhile, heat will continue to bake the west. Above normal rainfall will impact the eastern half of the country through the upcoming 7-day period. We forecast between 1.5” and 2.5” of rain across most central IN rain gauges in the upcoming 7-day period.
Forecast Period: 06.20.21 through 06.27.21
While we’re looking at an overall wetter than normal forecast period, there will be a multi-day stretch (centered on mid week) where we’ll enjoy dry conditions. This forecast period will be highlighted by additional storm potential with a cold front passing through to open the 7-day window, followed by the potential of heavy rain and stronger storms to close things out Friday into the weekend. Tuesday through Thursday will feature unseasonably cool and pleasant conditions, including the chance of some outlying areas to fall into the upper 40s. Warmth (and humidity) will build as we approach the weekend along with storm chances. While it’s still several days out, let’s circle Friday for the chance of heavy rain and stronger storms.
