While we look forward to temperatures in the 70’s tomorrow afternoon, we still need to get through a rather chilly morning. Sunrise temperatures will drop into the mid to upper 30’s! After a warm-up in the afternoon tomorrow, we will see a cold front approach for early Friday morning. This will bring a chance of showers…
The morning showers will be mainly confined to ours along and north of the Ohio River (top panel). By the afternoon, showers try to dissipate as they extend slightly southward (middle panel). Just as we think all is said and done, a disturbance will re-ignite showers for the evening and they will affect much of the region (bottom panel).
The above image shows an upper level jet on Friday evening (late, after 8 PM). Notice how we are located near the bottom right of that jet (yellow shading). It seems that there will be some upper level dynamics coming into play for the late evening and I wouldn’t be surprised if we heard a couple rumbles of thunder.
For the Saturday morning time period, there are some differences between the NAM and GFS model. The NAM keeps the showers around longer (middle panel) than the GFS model (bottom panel). It seems the latest runs are leaning more toward the NAM outlook, with a possibility of morning drizzle in areas of our region.
Then, as the weekend approaches, temperatures will warm into the mid 70s and eventually near 80 Sunday afternoon! It will be a dry spell, before the next system approaches…
Notice how this is a relatively strong system, with a 992 mb low over the Great Lake region (upper panel). A cold front extending from this low will bring a strong cool down to our region by Tuesday, with the 850 mb level dropping below the freezing point (lower panel). To put this into perspective, the current forecast calls for a high of 70 Monday, and only 55 for Tuesday!
Have a good evening!
