Another Gorgeous Day

Current Conditions

Temperature: 40 degrees, feels like 28 degrees
Dew Point: 25 degrees
Winds: S 17 mph
Pressure: 1006.4 mb
Visibility: 10 miles

This morning started out with 100% cloud cover and a temperature of 19 degrees. The rest of the morning was much of the same with winds out of the SE at 7 mph. At noon the temperature was 34 degrees and winds were SSE at 19 mph. Then early afternoon the clouds began to break and it remained partly sunny the rest of the afternoon. The temperature right now will be the high today, and not too shabby of one at that.

My prediction from yesterday was incorrect. In fact, we actually have a low pressure system sitting on our doorstep instead of a high pressure system. The temperature was also much warmer than yesterday not cooler.

Speaking of the low pressure system, there is one approaching western Minnesota and eastern Wisconsin causing a winter weather advisory for the area through Tuesday (figure 1).

Figure 1. Low pressure system heading towards eastern Wisconsin and likely bringing snow and sleet.

This can also be inferred from the pressure decrease from yesterday. Today the pressure is 1006.4 mb and yesterday it was 1017.6 mb.

These factors indicate that there will be snow tomorrow, although I couldn't say how much. The temperatures will continue to be high, probably in the low 20s due to the southerly winds that bring warm air to Wisconsin in the winter. I do think that the temperature won't climb to what it was today because of the cloud cover and precipitation expected.
