Satellite shows the block well in the Pacific: notice the moisture stream south to north almost to Alaska...then diving down the Canadian Rockies. Moisture then sails out of the Gulf to the East Coast. This pattern holding much of the week...so what you see is what you get until further notice.
Down on the ground...this is what the map looks like and don't look for many changes all too soon. In time..fronts will drop down from Canada in the East and will only serve to keep the weather the same.
Above...the upper air pattern this week: large upper low in Southwest and another Mid Atlantic...with a ridge over the Plains. The upper lows associated with cool - wet weather.
Above...amounts of rain expected over the next 7 days. Keep dry...stay safe.
