We are off to central Pennsylvania for the day’s forecast. It’s a land of hills and valleys, and all downstream from the Great Lakes. It’s often cloudy there.
At 1153AM, ET, Altoona was reporting a temperature of 55 degrees with clear skies. It’s predominantly dry across the region with a temporary swath of high pressure, however a trough in the Plains has developed a fairly robust area of low pressure in the Plains, indicating what’s expected this week in Altoona.
The sharp trough will remain over the Front Range, but a strong split flow jet will emanate from the trough and will run over the Altoona area for the duration of the forecast period. This boundary will act as a warm or stationary front, so the precipitation, which will be abundant through mid week, will be in the form of stratiform rain.
