NG cash market approaches 2018 lows

The Henry Hub cash market fell over 4% to 2.552 today putting it within striking distance of the 2.48 2018 low.  The first surge down occurred overnight followed by another leg down as a reaction to the storage number at 10:30am EST.  Interestingly, the March-April spread has gone negative for the first time in this calendar year's history suggesting commercials pricing in ample supplies by end of Winter.  The key assumption being that unseasonably warm temperatures continue...

If the market probes those 2018 lows, I would be looking to buy OTM calls for a short-covering rebound in prices reacting to a mean-reversion in Southern temperatures since it is still technically Winter.  The Google temperature mobile app is a good indicator for when temperatures will drop enough to cause short-covering.  I'm looking for a prediction of lows in the 20s and highs no greater than 40s in Raleigh, NC.  I've noticed a strong inverse correlation between Southeast temperatures and NG prices this year since inventories are currently 17.5% below the 5-year average and at almost 8-month lows.
