Current Official Hourly Observation (taken at :53 on the hour)
Today – Under the Dome – High 92
A dome of high pressure will help lift our high temps a few degrees above normal. This surface temp, pressure, and wind map produced by the GFS from 1 PM shows the dome of high pressure and a northeast wind (blue arrows).
An afternoon shower cannot be ruled out..
Thursday – More Humidity; Afternoon Rain Possible – Wake Up 72, High 94
High pressure remains. Throughout the day, the NE winds will turn, and become more southerly. This will push the dry air mass north and allow moisture (humidity) to begin to trickle back into Middle Tennessee by the late afternoon.
At least the added little bit moisture will give a slight chance for showers and thunderstorms during the afternoon.
Friday – Humidity Still Rising – Wake Up 72, High 92
More of the same: southern winds pushing in higher humidity (but still tolerable), with an afternoon rain chance.
The GFS weather model predicts rising dew points (moisture) around 7 AM Saturday morning.
Combine this moisture with a disturbance poised to move through Saturday/Sunday, and it’s looking to be a soggy weekend. Rain is more likely Sunday than Saturday. Humidity levels Sunday will be oppressively high.
Extended:
Rainfall totals Wednesday morning through Monday morning: 1.00″ to 1.75″.
