A strong cold front is crossing the region this morning associated with a deep area of low pressure in the Upper Midwest moving into the Great Lakes. The large wind field around this area of low pressure will drive breezy to windy conditions across the Tri-State for the next 48 hours.
Expect gusts to pick up in intensity through the morning hours with the most intense period likely between 10 a.m. and 3 p.m. Gusts of 40-45 mph will be likely and a few gusts to 50 mph are possible. A Wind Advisory has been issued for areas near Cincinnati. We’ll see a mix of clouds and sun today with falling temperatures early this morning. Temperatures will fall from the upper 50s at sunrise to the middle 40s very quickly. With some sunshine we will see only a slight rise back to 50 degrees for the afternoon. It will cool off further this evening into the 40s. Wind gusts will also lessen after dark but stay blustery at 10-20 mph.
After a chilly start in the upper 30s Friday morning, lots of sunshine will boost us back to around 50 degrees. This sunshine will promote deep vertical mixing in the atmosphere. This means that stronger winds aloft (still associated with the powerful low to our north!) will be able to be partially transported down to the ground. So expect breezy conditions again with daytime gusts of 30-40 mph likely. The winds will drop off rapidly after 4 p.m. as we cool. The cooling at the surface creates a temperature “inversion” meaning a warmer layer above the ground. Temperature inversions prevent that vertical mixing from occurring.
With clear skies and calming winds Friday night, temperatures will drop fast. Expect us to be in the 30s by the late evening hours with lows bottoming out near or just below freezing.
The upcoming weekend is look absolutely gorgeous and seasonable. Highs will be slightly below average on Saturday around 50 degrees. We will see another cool start in the lower 30s Sunday morning but daytime southerly winds will kick us up to almost 60 degrees.
The warming trend continues into next week. Another deep trough in the jet stream will develop over the mountain west creating a strong downstream ridge in the jet above the eastern U.S. This means nice weather and temperatures heading into the 60s.
That trough out west will strengthen and move east spawning another potentially powerful area of low pressure. There are still some specific timing differences among models but it appears that this system will move through around mid-week with more rain and wind.
