Lancaster was in the midst of a cold air damming situation when we looked at the city last weekend. A wave was moving into the Great Lakes, promising an influx of warmer conditions, but only if you believed one of the model outputs. Most every did believe the warming scenario, but perhaps not as passionately as the GFS. The GFS, it turned out, was on to something, as that model was close to the Monday high, but none of the outlets felt confident enough about forecasting that warm. Victoria-Weather was the closest, and won the forecast with ease.
Actuals: Sunday – High 44 Low 16
Monday – High 54, low 27
