Area Forecast Discussion National Weather Service Northern Indiana 704 PM EDT Thu Apr 22 2021
SYNOPSIS. Issued at 314 PM EDT Thu Apr 22 2021
A cool night is in store tonight with temperatures dropping into the 30s and frost is expected in eastern areas. Temperatures rise back to around 60 degrees on Friday ahead of rain arriving Friday night and continuing into Saturday. Looking ahead, temperatures warm to above normal early next week.
SHORT TERM. (This Evening through Friday) Issued at 314 PM EDT Thu Apr 22 2021
The trough that brought the cold wintry weather over the last few days exits the region to the east allowing ridging to continue to build into the area tonight. High pressure passes by to our south overnight though allowing another cold night with temperatures dropping towards the low to mid 30s as winds bottom out at around 5 kts tonight and with clear skies. One thing to watch would be how quickly the cloud deck can advance into the area tonight reaching southwestern locations during the early morning hours potentially stalling cooling in the upper to mid 30s. Eastern areas still will require a frost advisory.
Friday, the high is farther east allowing southwest warming winds and passing clouds. Highs will reach the upper 50s to around 60 degrees.
LONG TERM. (Friday Night through Thursday) Issued at 314 PM EDT Thu Apr 22 2021
Friday night the warm advection wing out in front of the approaching low pressure system will try to sprout showers across the area. Varying amounts of columnar saturation are shown in the models in regards to this wing lending to varying start times of the precip Friday night and likely to it being more spotty in nature. The main low passes by to the south of the region and will likely restrict the amount of moisture and instability making it north to the area. Even still, feel the residence time and the large scale lift associated with it, will help force enough precipitation to produce 0.25" to 0.75" rain. The increased cloud cover and rain will put a ceiling on high temperatures limiting them to the mid to upper 50s despite slightly warmer 850 Ts. Northwest winds and a secondary cold front behind the low may be able to provide another time for frost formation Saturday night if the rain ends early enough for drying out and decoupling. Have kept Sat night lows higher than 36 for this issuance as a result of the uncertainties listed above, but it will need to be watched in future shifts.
Another broader area of ridging associated with passing high pressure is expected to keep the area dry between Sunday and Tuesday as an area of high pressure settles in the southeastern US. Thereafter, a strengthening baroclinic zone out in front of a digging western US trough settles across the midsection of the county signaling a return to active weather for the middle to latter part of next week. Have also included some thunder for the Wed eve/night period with increased instability across the area.
AVIATION. (For the 00Z TAFS through 00Z Friday Evening) Issued at 658 PM EDT Thu Apr 22 2021
High pressure will provide VFR conditions through the critical TAF period. After daybreak Friday, clouds will return to the terminals ahead of a sprawling area of low pressure. Clouds may increase sooner than advertised, as the 18z FM group was added to address increasing afternoon wind.
