It has been another day with sunshine and high temperatures in the 30s and 40s. More snow and ice melted today and it will again Thursday through Friday. In addition to the warm weather…rain is expected. That combination will get rid of a lot of snow. Right now the cold air is north of the jet stream and out over the Pacific Ocean. The low over Texas is forecast to bring us rain Thursday.
By looking at the satellite image below…the structure of the clouds is a good indicator of the cold temperatures.
Tonight the sky will be mostly clear and the wind will be light. Put that together and moisture in the air from the melting snow…some locations will have fog late tonight.
The clouds will increase Thursday morning and the wind will increase from the southeast. This is all as low pressure tracks north and northeast. Rain is expected to move into eastern Iowa, from the south, around lunch time. Rain is forecast to be on and off through Friday morning before it tapers off. Thursday night the wind lightens up and it will remain warm with light rain. At this time areas of fog may form.
Rain amounts from this storm will be mainly 0.25-0.50” with isolated higher amounts along the Mississippi River. The map below is the rain forecast from Wednesday evening to Friday evening.
Friday will be a bit interesting. I am leaning toward some clearing of the sky to see some sunshine in the afternoon pushing temperatures in the mid and upper 40s. If the clouds hold together through the afternoon the highs will be cooler, more like upper 30s to near 40. A cold is forecast to cross the state late Friday night. High temperatures Saturday and Sunday will be much colder (20s) behind the front. The wind will be strong Saturday but weaken on Sunday.
High pressure will dominate the middle of the country for the first half of next week with dry conditions and relatively light wind. High temperatures will slowly warm back into the low 30s Tuesday and Wednesday. It will now be easier to warm up during the day since there will be a lot less snow on the ground due to the recent warm weather and rain.
