Think you might be confused: Anomaly number represents difference between normal and expected temp:

"I laugh at those red maps and it will never stop those cold blast".
In terms of what the forecast temp anomalies are...its actually the opposite:
The -2 or -3 F actually tells us that there will be no (or a weak) cold blast relative to normal temps. So for example my normal mean temp during that time (late November) is 52 F....so (even though my local forecast is for temps to by +5 lol) if I had a -3 F anomaly - my mean temp would be 49 F. Not really a big difference.
