Cool temperatures, actually near average for this time of the year, will keep into the region for the first half of this weekend as high pressure will dominate and bring with it a moderate northwest flow.
As the low moves off, a weak high pressure will keep the weather pleasant for Wednesday, with temperatures running 10 to 15 above normal - continuing the trend from the winter. A frontal system will start to approach the area on Thursday. As of now, the GFS is marking the chance of instability ahead of the front. Accentuating the timing of this frontal system, the forecast has a chance of showers overnight Thursday into Friday.
