Area Forecast Discussion . Correction National Weather Service Northern Indiana 1027 AM EDT Sat Jun 12 2021
SYNOPSIS. Issued at 348 AM EDT Sat Jun 12 2021
Hot weather is expected again today with storms developing during the afternoon, especially toward evening. The storms will likely be accompanied by strong gusty winds and torrential downpours. Highs will be near 90 today. Cooler, drier and less humid conditions will prevail Sunday through Thursday.
UPDATE. Issued at 1025 AM EDT Sat Jun 12 2021
No major changes to grids or thinking with respect to a very hot/humid summer day giving way to chances for widely scattered convection mid afternoon into this evening. An incoming weak sfc trough, enhanced by a Lake MI lake breeze, will likely be the focus for convection this afternoon. Lacking flow/forcing over the shallow front should limit coverage to widely scattered (20-50% coverage), roughly developing just west of I-69 mid afternoon, then spreading southeast from there with new development along outflow boundaries. Effective shear values in the 15-20 kt range should limit any organization to pulse or disorganized multicell, though DCAPE values into the 1000-1500 k/g suggest some wet microburst potential (isolated damaging wind threat) with SPC upgrading their day 1 outlook to marginal locally.
SHORT TERM. (Today and Tonight) Issued at 348 AM EDT Sat Jun 12 2021
More storms are likely again today as a front moves south during the afternoon and as the atmosphere destabilizes with conditions becoming hot and humid. Elevated concern with a potential of downbursts as DCAPE values top 1000 J/Kg. A local downburst yesterday at Three River produced a wind gust of 66 mph. Believe the environment this afternoon will be capable of producing isolated wind gusts in excess of 60 mph. Precipitable water values should rise close to 2.0 inches. A number of the Convective Allowing Models favor storms developing after 4 pm EDT with rapid growth and development . Have coordinated with the Storm Prediction Center and at the time of the Day1 outlook issuance they were not introducing a Marginal Severe Risk at that time, but it looks like they were becoming more favorable to a marginal risk to be introduced at the 13Z (9 AM EDT) update. There should be explosive storm growth late this afternoon as CAPE values rise rapidly to 2500 J/Kg. Although the potential of widespread flooding is low, extremely heavy rain RATES exceeding 5 in/hr are possible and could cause local flooding, especially over any urbanized areas.
LONG TERM. (Sunday through Friday) Issued at 348 AM EDT Sat Jun 12 2021
A cooler and dry period is ahead for much of the upcoming week with pleasant summer weather as a large high pressure area settles over the Midwest. Have kept Sunday through Thursday dry with highs close to 80 most days.
AVIATION. (For the 12Z TAFS through 12Z Sunday Morning) Issued at 645 AM EDT Sat Jun 12 2021
Scattered showers and storms are expected late this afternoon as a weak cold front approaches the area. Coverage will be on the lower side given weak forcing and confidence in impacts to the terminals remains low but will introduce a VCTS mention. Strong instability could support gusty winds and brief heavy rain where storms do develop. Otherwise VFR with light winds through the period.
