Weekly #AGwx And #Severe Weather Outlook…

I. Widespread area of below normal rainfall from the Plains into the Ohio Valley.

II. Anomalous heat bakes the West.

Widespread well above normal temperatures will bake the West this week while we remain seasonable to slightly below normal, locally.
Heavy, tropical downpours will impact the Southeast while the majority of the remainder of the country will remain on the drier side of normal.
7-day rainfall totals should only add up to between 0.10″ and 0.25″ for central Indiana.
The week isn’t expected to produce widespread, organized severe weather across our neck of the woods. Better chances of severe weather can be expected today across the upper Midwest and high plains.

Forecast Period: 08.15.20 through 08.22.20

Relatively quiet weather conditions can be expected across our region this week. A cold front will slip through the area Sunday and will offer up the best chance of getting precipitation throughout the upcoming 7-day period. Even this won’t be anything to get excited about, but there will be a broken band of showers and embedded thunder that scoots across the state for the 2nd half of the weekend as the cold front moves southeast. (Additionally, if viewing from northwest or west-central Indiana, you will have the chance of a passing thunderstorm later this evening as the front inches closer). Thereafter, generally dry and seasonable to slightly below normal temperatures can be expected as high pressure dominates. The one potential “interruption” to what will otherwise be a dry forecast has to do with a 2nd frontal boundary that will make a run at the region mid-to-late week. For now, we’re not excited about precipitation chances, but “isolated” shower coverage is possible by Thursday into Friday. Overall, we’re only expecting most central Indiana rain gauges to accumulate between 0.10″ and 0.25″ for the entire period.

I. Warmer and more humid air builds northeast through the period.

II. Rain and storms return.

While excessive heat isn’t expected, a much warmer and more humid pattern will emerge (compared to late) through the forecast period.
Above average rainfall is expected from the upper Midwest into the Ohio Valley.
Clusters of storms should lead to between 1” and 2” of rain for central Indiana by next Saturday morning. There will be locally heavier amounts.
Storm complexes will have embedded strong to severe thunderstorms this week. Biggest concern will be the potential of damaging straight line winds.

Forecast Period: 08.08.20 through 08.15.20

While we still have one more day of relatively low humidity, that will begin to change for the second half of the weekend. Temperatures will climb to seasonal and above normal levels this week as well. In short, after an unusually refreshing open to August, true late-summer conditions will build back into the region. Rain and storm chances will also increase substantially throughout the week. Some storm complexes will include heavy rain and embedded stronger storms. From this distance it’s hard to pinpoint what day will have the best chance of storms, but agriculture, turf management, and anyone with outdoor plans should prepare for multiple days with weather impacts through the upcoming week. Given the nature of this setup, some communities will likely deal with excessive rain totals by this time next week (unfortunately the pattern still looks wet beyond the period), with widespread 1” to 2” totals across the board.

I. Isaias set to impact the eastern seaboard early week.

II. Unseasonably cool air dominates the period from the Plains into the Ohio Valley.

Well below normal temperatures can be expected for the upcoming week from the Plains into the Great Lakes and Ohio Valley.
Above normal rainfall is expected from the Ohio Valley and into the eastern Great Lakes and along the East Coast.
We forecast between 1″ and 2″ of rain for central Indiana- most of which will fall now through Tuesday.

Severe: Widespread severe weather isn’t anticipated this week, with the exception of just east of the track of our surface low today (eastern KY, southeast OH, and northern VA) and into the Northeast Sunday.

Forecast Period: 08.01.20 through 08.07.20

Our weather will be dominated by a trough and associated low pressure through the early portion of the work week. Initially it’s a surface low that will provide periods of rain and embedded thunder through the weekend, but by the time we get to Monday and Tuesday, it’s upper level energy that will be responsible for scattered showers and thunderstorms. Periods of heavy rain can be expected this afternoon into tonight, especially across east-central Indiana. Thereafter, drier air will arrive for midweek. With the drier airmass in place, temperatures will fall into the mid-upper 50s (average low is in the middle 60s). Our next weather feature (a weak cold front) will arrive next Friday with the potential of scattered showers and storms.

Isaias will skirt the eastern seaboard through the early portions of the week. While not a particularly well organized storm, tropical storm and low end cat. 1 hurricane force winds can be expected from eastern portions of the Florida peninsula and up the Carolina coast, into New England by midweek.
