Period begins with cold front an advancing rain shield moving through the state. It has definitely been more stubborn than originally thought. The cold front and rain will quickly advance through the state overnight and be exiting the southeast by mid day Saturday. Cooler air will be lagging behind the front so under partly to mostly sunny skies we will warm up nicely. Cold and dry air filtering into the state will help with radiational cooling Saturday night. THis will help to drop the lows down into the low to mid 30s across the north. This will set the stage for a more widespread frost than originally thought. Will maintain the patchy approach for this forecast but that could change. Northwest sections may see their first freeze of the season as well. Cooler through the end of the period with surface high pressure in control. We will be sunny in the day and clear at night so temps back into the 30s and 40s will be common. In fact, more of the state could see frost on Sunday night with 30s nearly statewide. Have added mention of frost to the central third as well to account for this. The typically colder spots like the Ouachitas, and outlying areas along and north of 40 may be susceptible to frost.
Very tranquil to start the period with high pressure in control. With northwest flow aloft, dry and cooler air will persist. Clouds increase on Tuesday ahead of another cold front. Low pressure over the southwest U.S. will begin to push east. This will help to increase rain chances and drive the front on through the state. Timing differences and strength differences have led to lower end pops until better agreement can be reached. Overall pattern does favor rainfall. Thunderstorms and severe weather not expected. Temps will be below average through the period.
