REST OF TODAY:
Thinking the area extent of drizzle will diminish into the afternoon as slightly drier air filters in at the surface and weak disturbance moves east. Temps may come up a couple of degrees without drizzle: that means upper 20s to near 30 north/northwest, mid 30s DFW, and near 40 south of I-20.
A FREEZING RAIN ADVISORY remains in effect until 6pm TUESDAY for Parker, Denton & Collin counties and everyone north and west from there.
We’ve already seen a few icy spots in the Advisory area, especially where temps have gone into the 20s. That will continue to be the case throughout the day, even if it stops drizzling, there are still going to be icy patches, especially on elevated surfaces and bridges/overpasses.
As the next disturbance approaches from the west, more drizzle/light rain will begin to set in after sundown. Temps will be falling into the 20s farther south into the Metroplex and generally areas along and north of I-20. We could begin to see more icing on bridges/overpasses in the DFW area by 9 or 10pm tonight. Amounts will be very light, but it doesn’t take much to cause issues. More than likely, Tarrant, Rockwall and Dallas counties will be added to FREEZING RAIN ADVISORY later today.
Temperatures are expected to be in the 20s in the Metroplex and especially north and west….although freezing rain/drizzle is possible over all of our area tomorrow morning. Icing will be likely on bridges/overpasses and some secondary roads, sidewalks, parking lots. The freezing rain may start mixing with sleet early Tuesday over most of the area. Snow is more likely along the Red River. All amounts of wintry weather should be light (less than 1/10”), but a few spots could see slightly more. This does not look to be a repeat of early December’s ice storm with several inches of ice. But there will be the traditional slick spots on flyovers and bridges.
During the afternoon, temperatures will creep above freezing, especially along and south of HWY 380. Any leftover precipitation should be mainly liquid, with possibly a few sleet pellets mixed in. Road conditions should improve during the afternoon, but a few icy spots could linger in our northern counties even during the afternoon. All precipitation should end by evening Tuesday and travel conditions will show a marked improvement.
