(Monday)Slight cooling today; max temps dropped 3-4 degrees from yesterday(90 degrees at this sta); a warm up is expected the first part of the week but the air will be drying out and becoming less humid so even though the temp is rising, it still should be more comfortable; TRW activity is also expected to be more unlikely; nites expected to be slightly cooler too (in low 70's at obs time tonite) with high minimum temp records less likely to occur but once again El Cajon did set another high minimum temp record for today's date at 74 beating the previous record of 70 set in 2018; some slight cooling by late in the weekend |

(Tuesday)Another seasonable day (83 here); seasonable weather expected through Thursday but a rather potent heat wave is on the way from Friday through the Labor Day weekend; inland valleys could see temps as high as 100-115 and this heat will extend to the coast also with highest temps there 90-100; hottest days are supposed to be Saturday and Sunday with some moderation in the heat expected beginning Monday; so far, nites and early mornings are pleasantly cool with temps reaching the low 60's but with higher temps expected later in the week, that will probably change too |

(Thursday) Last of the really comfortable days as temps here rose 5-6 degrees from yesterday (88 here); heating up to start tomorrow with a nasty looking heat wave expected to last through the holiday weekend with Saturday and Sunday looking to be the hottest days with some valley high temps possibly nearing 110 and setting records with nights possibly being as warm as the upper 70's to around 80; then slightly cooler Monday into the middle of next week; will probably be the hottest days of this year and maybe years past; only bit of saving grace is that humidity is supposed to be low with offshore flow setting up which will increase both the temperature and the fire danger |

(Saturday)A day for the record books-hottest day I can remember in the nearly 45 years I have lived here; max temp at this sta was 107-a 17 degree rise from yesterday and for El Cajon at 114 breaking the previous record set of 107 set in 1984 and it was the highest max temp for ANY DAY on record dating back to 1899; some desert communities reached as high as 122 today; not much if any relief for tomorrow either; some cooling to begin Monday and into Tuesday but then a Santa Ana condition sets up the middle to latter part of next week possibly bringing more triple digit max temps again before another minor cool down begins by next weekend; nite time temps tonite are also about the warmest I have ever seen with readings above 80 at obs time which will no doubt aid in giving quick rise to temps in the morning |

(Sunday)Not as bad a day max temp wise as was forecast; only reached 102 here when forecast was calling for 110+; depending which station was used, El Cajon reached either 107 or 111; even San Diego (Lindbergh Field) reached 100 today; cooling trend has started but will be felt on the coast first starting tomorrow and inland starting Tuesday; relief will be short lived as a Santa Ana condition is due to set up by midweek bringing at least 90 degree + temps starting Wednesday into next weekend; nite time temps here are about 10 degrees cooler tonite at obs time than they were last nite |
