First Mesoscale discussion up now due to low level jet ramping up causing low level convergence. Forcing up precip in the form of freezing rain. The warmth of the roughly 850 mb layer is above freezing. This means that precip is falling melting and then re freezing on the ground. This is only the beginning of what looks to be a very large system impacting a great deal of the midwest. The 500mb map shows the scale of whats happening.
