From RAH :
The next chance of any precipitation will arrive on Tuesday, in association with the re-newed strong height falls accompanying the negatively-tilted trough and attendant Arctic cold front that will move
through the area late Tuesday/Tuesday night. Models have trended faster, more progressive with this system, sweeping it well out into the Atlantic waters Tuesday night. Given the faster, more
progressive timing with this system, the potential of seeing any significant accumulations from a rain to snow change-over, before the precipitation ends is becoming less and less.
