The low is typical in March, but the high is more typical of January.

That high is 1F above our average high in March. The low, however, is 2F above the average low for April.

Mid May to early June, diurnal range is a bit low for a sunny day here

ASKING SOMEBODY MORE KNOWLEDGEABLE THAN MYSELF.

If a strong cold front is passing through (usually creating a tenporary temperature inversion...??) and 850MB temps are BELOW 0C and light-moderate precipitation is forcasted does that signify snow? If so the GFS is signaling for possible snow in north central FL



And thank you to all who responded to my question above . Please keep responding even though it makes me feel even worse about my climate!

Forecast Lows & Max temps tomorrow.

The last time BDR(Bridgeport,CT) had a max of 15° in the month of February was in 1979! 2/17/79

The 17° in Islip & 14° in Boston would be the coldest February Max since 1996.

In other words, the last time Boston failed to warm past 14° in the month of February was in 1996.

Late August here in Madison, WI. Average highs cool down into the 60s by September, later in the month.

Don't take my word for it, but I think the answer is not always because a warm layer can exist between the surface and the 850 mb level which melts the snow before it makes it to the surface. However, the GFS does seem to be hinting at snow pretty far south, so I guess we will wait and see if it stays consistent. I hope someone else will comment on this because I confess that I'm not sure myself.

Thanks! Thats how I feel it seems like a strong front would create a inversion and therefore all layers below the 850MB line could be COLDER. However I would really like a expert to comment on this and light-moderate snow would be a incredible event in North-Central Florida!

The GFS and EURO show wintry weather in the southeast, I haven't looked into it. So busy with the storms up this way and the cold. USUALLY I never like to call for snow "after" a front because there's usually dry air behind it.

If 850mb temp is below 0C and you have an inversion that means the surface is in the teens or 20s F. (inversion is warmer above, not below)

but if GFS is showing precip with 850s below freezing, that's a start and an ingredient to get wintry weather.., have to check other things especially down south. What are the surface temps, how hard is the precip falling, soundings, wind, WetBulb, thickness of cold layer, ect, ect

Hope that helped
