Yesterday, we drove from Joplin, MO, to Indianapolis, IN, under clear, sunny skies, and generally nice weather. It was even a little chilly when we arrived in Indianapolis.
This morning has been mild, sunny, humid and still. I had a nice run, though it was humid:
National Weather Service (NWS) in Indianapolis, IN, forecasts (for Indianapolis, IN) a mostly sunny day, with a high temperature of 77 F. The winds will be from the northeast at 3-6 mph.
The NWS in Wilmington, OH, forecasts (for Columbus, OH) a mostly cloudy day, with 20% chance of rain, and a high temperature of 72 F. The winds will be from the northeast at 7-9 mph.
The NWS in Cleveland, OH, forecasts (for Lodi, OH) a mostly cloudy day, with a high temperature of 70 F. The winds will be from the northeast at 5-7 mph. This evening will be partly cloudy, with a low temperature of 51 F. Winds will be from the north at 5 mph, becoming calm after midnight.
The visible satellite imagery shows no clouds over our travel route so far this morning. This image has been excluded from today’s post.
The infrared satellite imagery shows no clouds over the travel route, either. This image has also been excluded from today’s post.
The water vapor imagery shows that we do have plenty of deep-layer moisture this morning.
The 12Z sounding from Wilmington, OH, shows a damp atmosphere below 750 mb. There was 0.73 inches of precipitable water present in the column this morning. There was no Convective Available Potential Energy (CAPE) or Convective Inhibition (CINH) present. There was a tiny thermal inversion near the surface, and the 0-3 km average lapse rate was 4.5 C/km.
The hodograph shows that there was 9 kts of low-level shear and 21 kts of deep-layer shear. Shear at all levels was due to a mix of speed and directional changes.
The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures, and high humidity (based on the surface dewpoint depressions). The skies are mostly clear, with a faint northeasterly breeze. There are no major frontal boundaries along our travel route this morning.
The surface pressure chart shows that we are under no strong pressure systems or gradients, and the RAP shows that none are expected to develop in the next six hours.
Synoptically speaking, the 300 mb NAM chart (from Unisys) shows that we will remain in the western edge of a small
The 500 mb NAM chart shows that there is no strong vorticity advection over the state today. This chart has been excluded from today’s post.
The 700 mb NAM chart shows no major pockets of rapidly-rising air along our route today. This chart has been excluded from today’s post.
The 850 mb NAM chart shows no strong thermal advection over the state today. This image has been excluded from today’s post.
The Precipitation chart shows that rain is unlikely along our travel route today. This chart has been excluded from today’s post.
Wilmington seems to think we will get some rain this afternoon (or at least a chance of it), but I am not seeing it. I think we’ll have another day of smooth sailing across the Midwest.
Thank you for reading my forecast.
