The cold air mass stationed over the Eastern Half of the US will continue to stick around for at least another 5 days, but slow, gradual warming will occur during this period. Here's an 8-day portrayal of forecast temperature anomalies compared to normal temperatures.

| Note: Anomalies are in CELSIUS |
Despite this cold air mass, warming is forecast by the GFS ensemble members. Below is an image of 10 days out temperatures.
Ensembles indicate the cold air mass over the US is forecast to dissipate as a warmer air mass moves in from the northwest US and Canada. Below is the Day 15 forecast temperatures by the same GFS ensemble members.
At this point, some GFS ensembles indicate strong warming is to take place in the Central US, but together they indicate the cold air mass fading and a modestly warmer air mass to move across the US.
