Thursday's Forecast:
Thursday starts with cloud cover as a weak system tracks across the Midwest. Forecast models remained consistent over the past few days, leaving the highest precipitation chance to our west and southwest across eastern Iowa and western Illinois. Cloud cover will then gradually decrease after midday, giving us some afternoon sunshine. That, along with a southeasterly wind will result in Rockford's fourth consecutive day with afternoon highs in the 40s.
"False Spring Arrives":
From there, "false spring continues". So much so that we enter a territory that we haven't entered since the middle of January, the 50s. The combination of partial sunshine and a light southwesterly wind will push highs in the low 50s Friday afternoon. Overnight lows will also trend upward, dropping into the upper 20s tonight, then low 30s Friday night.
Valentine's Day/President's Day weekend will also be spent in the 50s, though clouds will increase Saturday night into Sunday as an area of low pressure slides to our south. Considering how far south the track of the surface low has trended, rain chances this weekend remain very low. Hopping back into the temperature discussion, Saturday and Sunday's high of 53° lands exactly 20° above mid-February standards.
A secondary and slightly more potent storm system aims to lift into the central plains Monday. In doing so, it will drag a warm front through the region, allowing "false spring" to continue. Afternoon highs for the first half of the week will also end up 20° above average in the low 50s. Wednesday's warm up will mainly depend on the low's placement as it moves across the western Great Lakes.
