We made it through one of the chilliest stretches to start May in a while. There were readings in the Great Lakes and Upper Midwest that suggested that numbers, like morning lows around freezing, or stretches below 50, had not been seen since about 2013. This time of year, that reads more as late winter than late spring.

Finally, though, 10, going on 11 days in, the persistent eastern trough is breaking down, and warm air is flowing back north through the Eastern US. And it will persist, with warm forecasts expected for most.

It has also been a dry start to May. April Showers may be through, but May showers are appreciated, too. The jet structure is going to be lifted along the Canadian border, and will be pocked with short undercutting waves. Bundles of energy to bring some precipitation into the picture as well.

You may note that this is not a uniform color scheme. There remains some below normal precipitation in the west, but the good news is, that this typically dodgy area is actually not in a drought this year. They will withstand some dry weather .

The rain is going to come in places where it is needed. The southeast and northwest remain thirsty, but the Plains are going to warm up, and be satiated for the next couple of weeks.
