When will this cold spell end

I was recently asked when this cold spell will end. As if I was a soothsayer.

I took some introductory meteorological courses  in college, which classifies me as a novice in the field.

My interest in the weather at the moment:

• I'm hoping for rain so I can fill my pool, instead of having to pay for the water.

• It gets warm soon so I can use the pool.

From looking at various charts, we may see a warming trend near mid-month February.
