[su_note note_color=”#bceaed”]Today’s high in Blue Bell was
48º, 49°, not too far off from the new NBM forecast. I know a lot of phones and watches in the area probably showed highs of 50 or more.
The very localized temp readings you get on your watch are done from a network of weather spotters that do not necessarily adhere to the standards of measuring temperatures in a white louvered/ventilated wood box with double roof covering. It must be 2 meters above ground level over a grassy surface and at least 100 feet away from any concrete or other structure. (Called a “Stevenson Box”.)
And of course, Philadelphia Airport’s official reading is done in such an enclosure, but it’s near the river, at the far southeastern corner of our area. KPHL, Philadelphia Airport’s temperatures tend to run 1-3º higher than Blue Bell, KLOM.
Sundays’s predicted high is expected to be about 56º. [/su_note]
