Monday, Feb 20 (and weekend Sat Feb 18/Sun Feb 19))

Tonight the weather has strong winds. A strong low front centered near Omaha is pushing cyclonic winds towards us with gusts of roughly 15-20 mph. The sky is entirely overcast, and the weather services are expecting snow tonight but as of yet no snow has fallen. The temperature is 42° F and the dew point is 20°, snow is very likely to arrive tonight from the west. The sky is dark, since it was light out this morning at about 6:30 (though the sun rose at 7:00), I had hoped for a whisper of sunlight this evening. I will have to be patient, but I expect to see a sunsets before DST kicks in (I'm not going to check because that would spoil the fun).
Sunday saw the temperature peak at 39°, but by the time of my recordings it has dropped down to 30°F, with a 5 mph breeze from the S. The same low-pressure system that brought this warm air will soon bring precipitation, and the NWS predicts snow tomorrow.
On Saturday at 7:00 it was 30° F with no discernible breeze (although the internet tells me there is one), as the prevailing High pressure that had been dominating headed east while a massive low pressure system from the West and South replaces it. Cyclonic winds are pushing warm air in from the South, which will last through the weekend and we can expect to see another mild day tomorrow, followed by some storms on Monday or Tuesday.
