April was quite a roller coaster as far as temperatures were concerned, with cooler air returning as we wrapped up the month.
However, there were enough warmer days during mid-April to keep the overall temperature average for the month just about half a degree below normal.
Cooler than average temperatures have returned and will likely stick around the rest of this week. Average highs for this time of year are in the upper 60s.
An “Omega Block” in the jet-stream pattern will keep the pattern cool from the Ohio Valley into New England. The pattern is called an Omega Block because the upper-level weather features and jet stream look like the Greek letter Omega.
The pattern can get locked for several days – blocking weather systems from the west from moving eastward. Temperatures are usually cooler than average on the east side of the block, which is where the Ohio Valley will reside for most of this week. This will keep high temperatures in the lower to middle 60s through at least Thursday.
The weather pattern is expected to finally shift into a warmer pattern this weekend as the block slowly shifts east, allowing winds to become more southerly as opposed to northerly. This will allow warmer air that is building in the southern U.S. to shift northeastward into the Midwest and Great Lakes. When that happens, temperatures will rise back in the 70s and perhaps near 80 degrees, with the threat for any frost finally coming to an end.
As far as precipitation is concerned, despite occasional bouts of showers and storms, overall precipitation amounts will likely stay below normal.
For the month of April, the Dayton International Airport, the official measurement location, received 2.95 inches of rain; the average for this time of year is 4.09 inches — which put us more than an inch below normal.
However, the wet winter has our annual precipitation running above average by about three-quarters of an inch.
