So, we've got us a pre-Easter meteorological bonnet thing going on today and tomorrow. See, the high pressure system responsible for the clear skies is centered over the Canadian Maritimes. That will direct a shallow layer of cool, stable air over the city from off the ocean. The air is so stable it won't allow any mixing with warmer air above, thereby capping any heating. Highs today and tomorrow should only reach the mid 60s, well maybe upper 60s if everyone behaves. That's still ten degrees above normal, but not the mid 70s as previously hoped. If you want the warmer weather, head inland as the onshore flow is pretty weak.

The shallow layer of maritime air may also produce patchy fog overnight. What will it take to get the warm air here? A cold front of course. One will pass through on Sunday, sweeping away the cap and allowing the temperature to rise into the 70s on Sunday and Monday.

Not only was last month Central Park's wettest March, it was also the fourth warmest. Our scatterplot of all March mean monthly temperatures and precipitation totals shows what an outlier last month was. It was the mirror image of 1885, which had less than an inch of precipitation and was 18 degrees colder. Brrr.
