Area Forecast Discussion National Weather Service Northern Indiana 225 PM EST Thu Mar 4 2021

SYNOPSIS. Issued at 222 PM EST Thu Mar 4 2021

Dry and seasonable conditions will prevail into the upcoming weekend with a slow warming trend for the start of next week. Shower chances begin to increase Wednesday into Wednesday night.

SHORT TERM. (This Evening through Friday) Issued at 222 PM EST Thu Mar 4 2021

Upper level ridging will remain well west of the area with cyclonic flow around low pressure in eastern Canada keeping a cool, but generally dry flow across the region. A weak disturbance passing through the flow was stirring up clouds across mainly eastern sections with clearing expected by this evening with mostly clear/mostly sunny skies expected into Friday.

LONG TERM. (Friday Night through Thursday) Issued at 222 PM EST Thu Mar 4 2021

Upper level ridge will slowly edge east through the weekend, with temperatures slowly increasing a few degrees each day and then more aggressively starting Monday as trough across the western states moves onshore and continues to deepen. Looks like a rather strong influx of moisture from the Gulf of Mexico will occur given slower and deeper trend for the trough. Consensus has been to run with likely pops Wednesday into Wednesday night. Some concern slower timing trends will continue and will require additional adjustments, but for now will ride with what at least appears to be increasing confidence in best period of opportunity.

AVIATION. (For the 18Z TAFS through 18Z Friday Afternoon) Issued at 1210 PM EST Thu Mar 4 2021

Southern periphery of expansive high pressure over Canada will bring VFR conditions through this TAF cycle. Northerly flow will continue through the period . diminishing tonight with boundary layer decoupling and not as gusty Friday.

IWX WATCHES/WARNINGS/ADVISORIES. IN . NONE. MI . NONE. OH . NONE. LM . Small Craft Advisory until 4 AM EST Friday for LMZ043-046.
