Increasingly cold, arctic air will continue to slowly invade the region through Friday and even more rapidly from Saturday through Tuesday before a moderation in temperature occurs beginning Wednesday of next week. Patchy, light wintry precipitation is possible in Western portions of the local area on Thursday and Friday morning. A more significant round of wintry precipitation is possible area-wide from late Sunday into Monday.
...Regarding Temperatures & Wind Chill Conditions...
Daytime high temperatures will average the 30s Thursday through Saturday, mainly the 20s on Sunday and Monday, and the 30s again by Tuesday and Wednesday. Nighttime/early morning low temperatures will average the lower 30s Thursday and Friday, the low to mid 20s Saturday and Sunday, and the teens on Monday and Tuesday.
Wind Chill values will average the 20s throughout most of the period, except for the single digits and teens from Sunday through Tuesday morning.
...Regarding Patchy, Light Wintry Precipitation on Thursday Morning & Friday Morning...
Patchy, light wintry precipitation is possible in Western parts of the local region (generally West of a line from Canyon Lake to Dripping Springs to Lakeway) mainly between 5am and 9am on Thursday morning, and in the same general area mainly between 4am and 8am on Friday morning. Within this part of the local region, patchy, light ice accumulation is possible especially on elevated, metallic and other colder types of surfaces.
...Regarding A More Significant Round of Wintry Precipitation from Late Sunday into Monday...
Wintry precipitation appears likely area-wide from late Sunday evening or Sunday night into Monday. The potential exists for both freezing drizzle/freezing rain and snow across much of the area during this time period, with potentially significant impacts in at least some parts of the area. We are continuing to monitor this aspect of the situation with more detailed updates to follow, likely beginning tomorrow.
