( #NWSPhoenix): Seeing thunderstorms in northern Mexico like this is a more common site for the Monsoon NOT the end of March.

The storms to our south will help push a surge of moisture into #Arizona tomorrow, which will aid in shower and storm development in southern Arizona in the afternoon. #AZwx

( #NWSPhoenix): RECORD high temperatures were again abundant across the Southwest with readings shattering previous records by around 10°F.

These also tied or exceeded ALL-TIME MARCH RECORDS again today. More of the same tomorrow before slight cooling arrives Sunday. #AZwx #CAwx #wx #wxsky

( #NWSPhoenix): Latest water vapor satellite depicts an intense area of high pressure centered over #Arizona. High pressure of this magnitude is similar to what we would see in the summer. Very dry air is encircling the high (dark orange colors) which is keeping skies clear over the Desert SW. #AZwx
