Clouds and near-record warmth will be the weather story for the next week across the Rock Hill area and the rest of the Carolinas.
The early-January pattern has flipped with a dip in the jet stream now covering the western United States and warm air surging into the East. The government’s meteorologists expect mild conditions to remain into at least the first few days of March.
The persistent mild pattern began Feb. 6, and Rock Hill’s high temperatures have been in the 60s or warmer all but two days since. Morning lows, which typically are in the mid 30s at this time of year, have averaged 44 degrees in Rock Hill over the last two weeks.
“Chances for rain and well-above-average temperatures will remain through the next week,” National Weather Service meteorologist Lauren Carroll said Monday.

The warm temperatures will be most noticeable during the night hours, but afternoon highs could threaten records at least a few days this week.
A pocket of cool air that was trapped across the Piedmont was responsible for chilly conditions Monday, but forecasters expect milder air to arrive by Tuesday morning. The Weather Service’s Sandy LaCorte said the warmer air likely will cause fog that could last into the mid-morning Tuesday.
But once the fog dissipates, temperatures are expected to climb into the low 70s. Mid 70s are forecast Wednesday and Thursday. Forecasters say Friday’s outlook is a bit tricky, as a cold front might push down from Virginia for the day before retreating northward again early Saturday.
That will set the stage for a warm weekend, with highs each day in the mid 70s.
Overnight temperatures will be very mild, with lows in the upper 50s to near 60 degrees.
The balmy temperatures won’t be accompanied by sunshine much of the time. LaCorte said a moist southerly flow will bring clouds, although breaks of sunshine are likely most days this week.
A few showers are possible Wednesday and again over the weekend.
