It has indeed been an active day in weather. It may not have been as meteoric a storm as some had predicted in Eau Claire, or even in the Upper Midwest, but it brought about quite a bit of strange and unfortunate weather that has made headlines the country over. Let us begin today by looking at Eau Claire.
The temperature was a mild 35° F at 7:00 PM tonight, making for the second mild day despite the incoming cold front. There was a hardly a mere whisper of wind when I checked, but NOAA and Wunderground assure me that there is in fact light wind from 5-10 mph. The sky was overcast, and the barometric pressure was at 998 mb -- on the rise after a dip at around noon as the center of the Low Pressure air mass passed directly overhead. Most noticeable about today's observation was the humidity, for the second straight day one can almost taste the air. The humidity almost lends a summer-like atmosphere to the mild temperatures.
The graphs below from Wunderground show a nice correlation between pressure and wind speed/direction, and I decided to include them today to illustrate the way in which air masses move over space, and how air flows into the center of low pressure. As the center of low pressure passes over us and grows further away, wind directions and then speeds change.
