YAYAY...A high pressure system is moving in to create nice conditions for warm temperatures later this week

We did end up receiving about 1 inch in snowfall accumulation last night.

Today's high was 43F. The current temperature is at 39F, but feels like 33F. Today's winds are coming from the NW around Humidity is at 46%, with a dew point of 20F, and a barometric pressure  mph.  Today's barometric reading is at 30.01. Looking at the surface map below we can see that the low pressure systems that were located in the west yesterday have worked their way to the Midwest. We can also see that there is a cold front associated with these fronts, as well as a line of thunderstorms.



Looking at the jet stream map we can see where the two air jet streams are merging. This matches quite well with both the cold front on the surface map, as well as the wind and temperature maps below. The jet  stream map shows where air masses with significant differences in temperature are colliding.  In the Midwest, especially, we can see where the polar and tropical jet stream air masses  are merging.

Again, looking at the wind map we can see where this cold fronts is located. We can determine this by looking at the line like feature that is associated with a change in wind direction.

Looking at the temperature map, again, we can see how the current temperatures correlate with both the high and low pressure systems, the wind map, and the jet stream. We can see where there is a dramatic difference in the temperature gradient change. When comparing this to the surface, jet stream, and wind map we can see the influences all these factors play on the temperature of a given area.


Tonight's forecast calls for a low of 25F, with winds continuing to come from the NW around 10 mph.
