Warm Wednesday, Cold & Wet Thursday.

The first map on the right, courtesy of the OK Mesonet, shows the high/low temperatures across the state so far today; obviously another very warm, spring day. Wednesday will be much the same. Then, there is Thursday….and I can hardly believe what I am seeing right now.

A very strong cold front will be pushing across the state Wednesday night followed by dramatically colder conditions all day Thursday. Consider this: The high temperature Wednesday afternoon will be near 80, afternoon temperatures on Thursday will be closer to 40 and some of the guidance we are receiving suggests it may be in the 30s for at least part of the day. That is more like what would be expected in Winter, not early May. Needless to say, we are looking at setting some records on Thursday for the coolest daytime high for that date.

Along with the much cooler temperatures will be cloudy skies, strong northerly winds, and periods of rain and showers. The second map on the right shows the QPF estimate for the next five days. As you can see, the real bulls eye for precipitation is well north of us, but we still stand to pick up ½ inch or more with most of that occurring from Wednesday night through the day Thursday. There may be a few lingering light showers into Friday, but after that we should be dry.

As the cold front is pushing through the state late Wednesday and overnight, there may also be some storms, but right now it appears that the severe threat will be minimal. Most of the forcing looks to be well behind the cold front which is why most of the rain will likely linger through much of the day Thursday.

Friday morning could also set some records. Our latest freeze date is May 2, of 1909, but Friday morning will be close. Some of the guidance we are receiving strongly suggests below freezing temperatures, clear skies, and light winds. But, the caveat is the clear skies and light winds. Other guidance would keep us with lingering clouds through the morning hours and whether or not the winds calm down is another issue. Have decided to err on the side of caution, and therefore put down a low that morning of 32 degrees; wishing and hoping that it does not get that cold. At any rate, any tender plants that are out will probably require some protection.

Temperatures during the day Friday will also be chilly with highs only into the 50s and quite possibly setting more records. Saturday morning could also see temperatures in the 30s and the possibility of a frost or light freeze. After that, things will be gradually moderating going into the following week.

So, stay tuned and check back for updates.
