From jeff:
Arctic air mass is well in place this morning with freezing temperatures roughly from Wharton to Katy to Tomball to Conroe.
Radar indicates increasing returns moving up the coast from S TX and this is being supported by surface observations showing light rain and drizzle around Corpus and Rockport. Interestingly snow flurries have been reported over the northern part of central TX and the Hill Country this morning. Lift will be increasing today across the region as the next impulse from the WSW moves across the state. Expect drizzle and light rain to gradually increase throughout the day. Luckily the temperatures are at their lowest point currently and should rise 2-4 degrees today bringing most of the area above freezing. NW counties from roughly College Station to Huntsville may barely reach 32 today and drizzle/light rain there this afternoon could form into a thin layer of ice. Southward there will likely not be any ice accumulations as surface temperatures hover in the mid to upper 30’s.
For tonight freeze line will move only slightly southward likely reaching a Columbus to Conroe line, so the continued light drizzle and light rain will only potentially be a problem in those areas to the NW of this line. Expect amounts to be generally less than .05 of an inch. Should not see any problems across the Houston metro area.
Cloudy and cold conditions continue into much of next week with highs likely remain below 50 for the next 3-5 days and lows in the 30’s. Bouts of rainfall will cross the area every 12-24 hours as the pattern remains nearly unchanged. Secondary surge of arctic air will arrive on Monday and help keep the area cold…but the good news is that this air does not look as cold as before and should keep the threat for winter precipitation out of the forecast.
Note: Record low maximum for today at IAH is 45 degrees and this will likely fall by several degrees.
