likely overnight min Saturday will be in the 50s with the rain and mild airmass. good chance we'll break the daily record min by a good amount. from the NWS New York

After a relatively cold low of 9F/-13C yesterday morning, it reached 50F/10C at 7pm today, with 30mph/50kph wind gusts from the SW. Warm and damp tonight from some light rain earlier. Decent temperature variability, much better than the 40/30 days that have happened often lately (4/-1C). 9F isn't far below average, but it felt like it with how mild this month has been (11F above average, December was +7F).

However, there's finally a good chance for significant snow. With only 2.8" since November 12th, and most of that coming on the 31st, a good snowfall and a stretch below freezing is long overdue. I'm excited. The early NWS forecast has Milwaukee getting 7 to 12 inches (18 to 30cm) on Saturday and Sunday. The 6-10 and 8-14 day outlooks finally have some blue (cold) over the area, instead of constant above-average.

There have been a lot of winter temperature and precipitable water records set and broken in recent years here.

Possibility of a derecho has been mentioned for tonight. Fortunately the hatched area for EF2+ tornadoes has been taken out with SPC's latest update for the overnight hours. Damaging winds are the primary threat.
