Yesterday, was a beautiful day. We did some exploring in Chicago, and then drove to Peoria in nearly perfect (albeit humid) weather. There were only a few light clouds, no breeze, and mild temperatures.
This morning has been mild, sunny and still.
The NWS in Lincoln, IL, forecasts (for Peoria, IL) a mostly sunny day, with a high temperature of 81 F. The winds will be from the northeast at 5-9 mph. This evening will be clear, with a low temperature of 60 F. Winds will be from the northeast at 6 mph, becoming calm after midnight.
National Weather Service (NWS) in Tulsa, OK, forecasts (for Tulsa, OK) a mostly sunny day, with a high temperature of 90 F. The winds will be from the northeast at 5-10 mph. This evening will be partly cloudy, with a low temperature of 66 F. Winds will be from the northeast at 5-10 mph.
The visible satellite imagery is unavailable at this time.
The infrared satellite imagery shows no thick clouds along our route this morning. This image has been excluded from today’s post.
The water vapor imagery shows that we will pass through the southwestern edge of the trough and into deeper moisture.
The 12Z sounding is unavailable at this time.
The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures and high humidity (based on the surface dewpoint depressions). The skies are clear and the winds light through most of our route. There are no major frontal boundaries over our route this morning.
The surface pressure chart shows no strong pressure systems or gradients over our route, so far this morning. The RAP shows that no major pressure systems or gradients are expected to develop over the next six hours.
Synoptically speaking, the 300 mb NAM chart (from Unisys) shows that we will drive perpendicular to the trough, and exit its southwestern extent, as it continues to move east.
The 500 mb NAM chart shows no strong vorticity advection over the state today. This image has been excluded from today’s post.
The 700 mb NAM chart shows no large pockets of rapidly-rising air. This chart has been excluded from today’s post.
The 850 mb NAM chart shows no strong thermal advection over our route today. This chart has been excluded from today’s post.
The Precipitation chart shows that rain is unlikely in Illinois today. This chart has been excluded from today’s post.
I am expecting a pleasant, but humid day today along our travel route from Illinois to Oklahoma. The temperature will be warmer farther south, but I don’t expect precipitation along the way.
