Area Forecast Discussion National Weather Service Northern Indiana 242 PM EDT Sat Jun 3 2023 .SYNOPSIS... Issued at 237 PM EDT Sat Jun 3 2023 Showers and thunderstorms this afternoon are expected to taper off this evening. Behind the boundary forcing today's showers and storms, dry air returns and continues through much of the work week. While there is a chance for showers again on Tuesday, it's a low chance. Temperatures trend back towards seasonable between today and the work week. Scattered showers and thunderstorms are expected this afternoon, becoming isolated this evening before tapering off. Otherwise, expect partly to mostly cloudy skies with highs in the upper 80s and low 90s. Lows tonight will drop into the 50s. Dry conditions persist Sunday and Monday, then we see a slight chance for rain showers late Tuesday. Dry conditions return for the remainder of the work week. Highs will be in the low to mid 80s until Tuesday, then drop into the 70s and low 80s until next Friday. && .SHORT TERM...(Today and Tonight) Issued at 237 PM EDT Sat Jun 3 2023 As expected, the area of warmer mid level temperatures shifted off to our southwest this morning and dew points approaching 60F moved into our northeast. As a boundary collocated with a strung out area of mid level vorticity sinks southeast through the forecast area around 18z and a lake breeze forms, the chance is there to sprout showers and thunderstorms as adequate moisture and instability along with the lift will be present for storms today. A small area of surface moisture (~60F dew points) and low level moisture (850 mb dew points above 10C) in this area indicates the potential for locally heavy rain. While storms may be able to initially have some motion to them, once they grow, there's a chance they slow down some. As such, locally moderate to heavy rain is a threat. With the advancing area of moisture indicated by the PWATs, the chances to tap into DCAPE seem to have dwindled. Perhaps some light gusty winds could be had, but without the better shear, it'll be hard to achieve the severe threshold. With weaker mid level lapse rates around 6 or 6.5 C/km as well as the moist lower levels being more conducive to hail stone melting, hail is expected to remain below severe thresholds as well. With much drier air coming in behind the aforementioned boundary, dew points are expected to drop and the storms will be able to dissipate this evening. Lows tonight will be in the low 50s to low 60s, around 5 to 10 degrees lower than last night. Sunday is right back into the drier airmass on north and east surface winds. The drier air is expected to limit the mixing to around 850 mb allowing for cooler highs in the low to mid 80s at best. The lingering low level jet will also allow for light breezes approaching 20 mph.&& .LONG TERM...(Monday through Saturday) Issued at 237 PM EDT Sat Jun 3 2023 Behind the boundary from today, an upper low level pressure settles into the Northeastern CONUS. Meanwhile, as a low pressure system ejects off of East Asia, it extends an upper jet farther east into the North Pacific. As it does so, the location for a low pressure system shifts towards the Aleutian Islands. This shifts the position of the upper ridge to the Western CONUS from over the Great Lakes allowing for a wave train shift during this upcoming work week. This allows the local area to trend cooler towards more seasonable temperatures in the upper 70s to low 80s. The northerly flow will also act to keep us in the dry air restricting the amount of precipitation chances through much of the upcoming work week. The one time during this work week we'll have to watch for rain will be along an axis of higher theta-e air collocated with 50 degree sfc dew points that comes through Monday night into early Tuesday. Both the GFS and NAM are keying into this as having an increased rain chance, but perhaps their higher moisture bias may be falsely creating precipitation. The ECMWF is much quicker bringing this moisture axis through meaning any extra oomph from diurnal instability will be minimized. Will be consistent with previous shift and continue the mention of rain mainly during late Monday night/early Tuesday morning. Our next chance for rain won't come until later Saturday/Saturday night as a cold front, potentially with an area of low pressure forming along it, approaches from Central Canada. Both the GFS and the ECMWF are limiting instability along this front as it approaches outside of peak heating.. && .AVIATION...(For the 18Z TAFS through 18Z Sunday Afternoon) Issued at 126 PM EDT Sat Jun 3 2023 Showers and thunderstorms will be possible today at TAF sites mainly after 20z today. The general trend with these storms will be towards Lake Michigan so there is a chance that FWA gets missed completely by them. Storms dissipate by 00z. There could be brief flight condition reductions as storms pass overhead of the terminals. Beyond that, flight conditions revert back to VFR tonight into Monday. Winds will be oscillating between northerly and easterly during this period with occasional afternoon gusts to 20 kts. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
